Available in PDF, EPUB and Kindle. Book excerpt: Thermal transport across the interfaces between few-layer graphene sheets and soft materials exhibits intriguing anomalies when interpreted using the classical Kapitza model, e.g., the conductance of the same interface differs greatly for different modes of interfacial thermal transport. Using atomistic simulations, we show that such thermal transport follows a nonlocal flux-temperature drop constitutive law and is characterized jointly by a quasi-local conductance and a nonlocal conductance instead of the classical Kapitza conductance. The nonlocal model enables rationalization of many anomalies of the thermal transport across embedded few-layer graphene sheets and should be used in studies of interfacial thermal transport involving few-layer graphene sheets or other ultra-thin layered materials.

This book was released on 2020-04-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanocomposites with Carbon-based nanofillers (e.g., carbon nanotubes, graphene sheets and nanoribbons etc.) form a class of extremely promising materials for thermal applications. In addition to exceptional material properties, the thermal conductivity of the carbon-based nanofillers can be higher than any other known material, suggesting the possibility to engineer nanocomposites that are both lightweight and durable, and have unique thermal properties. This potential is hindered by thermal boundary resistance (TBR) to heat transfer at the interface between nanoinclusions and the matrix, and by the difficulty to control the dispersion pattern and the orientation of the nanoinclusions. Thermal Behaviour and Applications of Carbon-Based Nanomaterials: Theory, Methods and Applications explores heat transfer in nanocomposites, discusses techniques predicting and modeling the thermal behavior of carbon nanocomposites at different scales, and methods for engineering applications of nanofluidics and heat transfer. The chapters combine theoretical explanation, experimental methods and computational analysis to show how carbon-based nanomaterials are being used to optimise heat transfer. The applications-focused emphasis of this book makes it a valuable resource for materials scientists and engineers who want to learn more about nanoscale heat transfer. Offers an informed overview of how carbon nanomaterials are currently used for nanoscale heat transfer Discusses the major applications of carbon nanomaterials for heat transfer in a variety of industry sectors Details the major computational methods for the analysis of the thermal properties of carbon nanomaterials
Book Synopsis A First-principles Investigation of the Transition Between Two- and Three-dimensional Thermal Transport in Graphene and Graphite by : Patrick Strongman
Download or read book A First-principles Investigation of the Transition Between Two- and Three-dimensional Thermal Transport in Graphene and Graphite written by Patrick Strongman and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional materials have become a popular research area over the past two decades because of their unique physical properties. The low dimensionality of these materials leads to interesting, and useful, transport properties such as thickness-dependent band gaps and high electrical and thermal conductivity. These materials have applications in nanoelectronics, optoelectronics, and thermoelectric energy generation, the performance of which depends sensitively on understanding and controlling how heat transport occurs. Most low dimensional materials can be derived by isolating them from their bulk counterparts, which are often comprised of stacks of the two-dimensional layers that are weakly bound together. These layered bulk materials often maintain some of the two-dimensional characteristics of their monolayer form because of the weak interlayer bonds. One common example of such a "quasi-2D" material is graphite, which is made of layered carbon sheets, i.e. graphene. When going from graphite to graphene the room-temperature in-plane thermal conductivity varies from approx. 2000 W/m K to 5800 W/m K, respectively. Both values are exceptionally high, but there is still a large difference between the two. Nevertheless, the majority of studies focus either on the bulk or low-dimensional versions of materials, with little focus on how the transition from 3D to 2D influences the microscopic properties and transport characteristics. The purpose of this study was to explain how the thermal transport properties of layered materials transition between two and three dimensions. Graphene and graphite were used as simple materials to model this transition. The thermal transport properties were calculated from first-principles using density functional theory (DFT) and iterative solutions to the Boltzmann transport equation (BTE). The transition between two and three dimensions was modelled by systematically moving the layers of graphite apart from each other until they were essentially isolated graphene sheets. The converged $\kappa$ values of the limiting cases of graphite and graphene agree with experimental measurements and previous calculations, with the stretched cases showing a monotonically increasing thermal conductivity from $\kappa_{\text{graphite}}$ to $\kappa_{\text{graphene}}$. Surprisingly, the largest variation in the thermal transport properties resulted from changes in the phonon dispersion. This is contrary to the previous belief that the difference in $\kappa$ resulted from certain three-phonon selection rules in graphene, which reduce the scattering probability, and do not apply to graphite. The selection rules appear to mostly still apply to graphite and the stretched graphite cases, indicating that the primary mechanism resulting in the differences between $\kappa_{\text{graphene}}$ and $\kappa_{\text{graphite}}$ was the shape of the phonon dispersion, and a corresponding shift in the phonon DOS. This type of analysis could be applied to other layered materials in the future to identify materials with the potential to be exceptional thermal conductors.

Available in PDF, EPUB and Kindle. Book excerpt: As the electronic industry aggressively moves towards nanometer designs thermal issues are becoming increasingly important for the high-end electronic chips. One of the approaches to mitigate the self-heating problems is the high-heat-flux hot-spot removal via incorporation into the chip designs of materials with the high thermal conductivity. Graphene is found to be one of the best known heat conductors, thus it can be used in nanoelectronic and optoelectronic devices as a heat spreader component. Graphene, the latest isolated allotrope of carbon made of individual atomic sheets bound in two dimensions, shows many remarkable properties. A non-contact method of measuring G peak position of the Raman spectrum as a function of both the temperature of the graphene sample and the power of the heat source was used to measure the thermal conductivity of graphene. The samples in the experiment had approximately rectangle geometry and the assumption about the plane heat wave was used for the data extraction. In this dissertation research we propose to develop a model and numerical procedure for the (i) accurate modeling-based data extraction for the thermal conductivity measurements; and (ii) simulate heat propagation in semiconductor device structures with graphene layers incorporated as heat spreaders. To achieve the goals of this dissertation research we simulated the heat transport in graphene using the finite element method (FEM) with the help of COMSOL software package, which solves numerically the partial differential equations. The modeling based data extraction was necessary to determine thermal conductivity of the graphene flakes of arbitrary shape. It also substantially improved the accuracy of the measurements. The simulation of heat propagation in device structures with graphene heat spreaders allows one to assess the feasibility of the graphene high-heat-flux thermal management. We focused on understanding how thermal transport is influenced by a surface geometry of the sample and geometries of the heat sources. The simulation results showed that the size, shape and heat source geometry impact heat propagation in different ways and have to be included in the experimental data extraction. The simulation procedure provided a necessary input for next experiments on heat conduction in graphene structures e.g., graphene multi-layers and graphene-heat sink structures and other device-level thermal management applications. It was found that the incorporation of graphene or few-layer graphene (FLG) layers with proper heat sinks can substantially lower the temperature of the localized hot spots. The developed model and obtained results are important for the design of graphene heat spreaders and interconnects and lead to a new method of heat removal from nanoelectronic and 3-D chips.

Download or read book Experimental and Theoretical Investigations of Thermal Transport in Graphene written by Mir Mohammad Sadeghi and published by . This book was released on 2015 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphene has been actively investigated because its unique structural, electronic, and thermal properties are desirable for a number of technological applications ranging from electronic to energy devices. The thermal transport properties of graphene can influence the device performances. Because of the high surface to volume ratio and confinement of phonons and electrons, the thermal transport properties of graphene can differ considerably from those in graphite. Developing a better understanding of thermal transport in graphene is necessary for rational design of graphene-based functional devices and materials. It is known that the thermal conductivity of single-layer graphene is considerably suppressed when it is in contact with an amorphous material compared to when it is suspended. However, the effects of substrate interaction in phonon transport in both single and multi-layer graphene still remains elusive. This work presents sensitive in-plane thermal transport measurements of few-layer and multi-layer graphene samples on amorphous silicon dioxide with the use of suspended micro-thermometer devices. It is shown that full recovery to the thermal conductivity of graphite has yet to occur even after the thickness of the supported multi-layer graphene sample is increased to 34 layers, which is considerably thicker than previously thought. This surprising finding is explained by the long intrinsic scattering mean free paths of phonons in graphite along both the basal-plane and cross-plane directions, as well as partially diffuse scattering of phonons by the graphene-amorphous support interface, which is treated by an interface scattering model developed for highly anisotropic materials. In addition, an experimental method is introduced to investigate electronic thermal transport in graphene and other layered materials through the measurement of longitudinal and transverse thermal and electrical conductivities and Seebeck coefficient under applied electric and magnetic fields. Moreover, this work includes an investigation of quantitative scanning thermal microscopy measurements of electrically biased graphene supported on a flexible polyimide substrate. Based on a triple scan technique and another zero heat flux measurement method, the temperature rise in flexible devices is found to be higher by more than one order of magnitude, and shows much more significant lateral heat spreading than graphene devices fabricated on silicon.
Book Synopsis Experimental Investigation of Thermal Transport in Graphene and Hexagonal Boron Nitride by : Insun Jo
Download or read book Experimental Investigation of Thermal Transport in Graphene and Hexagonal Boron Nitride written by Insun Jo and published by . This book was released on 2012 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional graphene, a single layer of graphite, has emerged as an excellent candidate for future electronic material due to its unique electronic structure and remarkably high carrier mobility. Even higher carrier mobility has been demonstrated in graphene devices using hexagonal boron nitride as an underlying dielectric support instead of silicon oxide. Interestingly, both graphene and boron nitride exhibit superior thermal properties, therefore may potentially offer a solution to the increasingly severe heat dissipation problem in nanoelectronics caused by increased power density. In this thesis, we focus on the investigation of the thermal properties of graphene and hexagonal boron nitride. First, scanning thermal microscopy based on a sub-micrometer thermocouple at the apex of a microfabricated tip was employed to image the temperature profiles in electrically biased graphene devices with ~ 100 nm scale spatial resolution. Non-uniform temperature distribution in the devices was observed, and the "hot spot" locations were correlated with the charge concentrations in the channel, which could be controlled by both gate and drain-source biases. Hybrid contact and lift mode scanning has enabled us to obtain the quantitative temperature profiles, which were compared with the profiles obtained from Raman-based thermometry. The temperature rise in the channel provided an important insight into the heat dissipation mechanism in Joule-heated graphene devices. Next, thermal conductivity of suspended single and few-layer graphene was measured using a micro-bridge device with built-in resistance thermometers. Polymer-assisted transfer technique was developed to suspend graphene layers on the pre-fabricated device. The room temperature thermal conductivity values of 1-7 layer graphene were measured to be lower than that of bulk graphite, and the value appeared to increase with increasing sample thickness. These observations can be explained by the impact of the phonon scattering by polymer residue remaining on the sample surfaces. Lastly, thermal conductivity of few-layer hexagonal boron nitride sample was measured by using the same device and technique used for suspended graphene. Measurements on samples with different suspended lengths but similar thickness allowed us to extract the intrinsic thermal conductivity of the samples as well as the contribution of contact thermal resistance to the overall thermal measurement. The room temperature thermal conductivity of 11 layer sample approaches the basal-plane value reported in the bulk sample. Lower thermal conductivity was measured in a 5 layer sample than an 11 layer sample, which again supports the polymer effect on the thermal transport in few-layer hexagonal boron nitride.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanocomposites based on graphene dispersed in matrices of soft materials are promising thermal management materials. Their effective thermal conductivity depends on both the thermal conductivity of graphene and the conductance of the thermal transport across graphene-matrix interfaces. Here we report on molecular dynamics simulations of the thermal transport across the interfaces between defected graphene and soft materials in two different modes: in the across mode, heat enters graphene from one side of its basal plane and leaves through the other side; in the non-across mode, heat enters or leaves a graphene simultaneously from both sides of its basal plane. We show that, as the density of vacancy defects in graphene increases from 0 to 8%, the conductance of the interfacial thermal transport in the across mode increases from 160.4 16 to 207.8 11 MW/m2K, while that in the non-across mode increases from 7.2 0.1 to 17.8 0.6 MW/m2K. The molecular mechanisms for these variations of thermal conductance are clarified by using the phonon density of states and structural characteristics of defected graphenes. On the basis of these results and effective medium theory, we show that it is possible to enhance the effective thermal conductivity of thermal nanocomposites by tuning the density of vacancy defects in graphene despite the fact that graphene s thermal conductivity always decreases as vacancy defects are introduced.

Download or read book Four-probe Thermal Transport Measurements of Few-layer Graphene and Ultrathin Graphite written by Eric Ou and published by . This book was released on 2020 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique combination of mechanical, electrical, and thermal properties of graphite and its derivatives, such as graphene and carbon nanotubes, make graphitic materials desirable for a number of technological applications as well as a platform for studying various transport phenomena, especially at the nanoscale. Although it has been more than a decade since graphene was first successfully isolated, discrepancies between the results of theoretical and experimental studies have not yet been resolved and the answers to many fundamental questions concerning the details of thermal transport in graphene are still subject to debate. The presence of unknown contact thermal resistance has limited prior two-probe thermal transport measurements of suspended graphene samples. This work utilizes a four-probe thermal measurement technique to measure few-layer graphene and ultrathin graphite samples. This technique has the ability to measure the intrinsic thermal conductance of suspended samples and to isolate the contact thermal resistance between the sample and measurement device. By eliminating error due to contact thermal resistance and developing a clean method for transferring thin-film samples, the true intrinsic thermal properties of graphene can be realized, potentially leading to the observation of unique transport phenomena such as hydrodynamic phonon transport

Available in PDF, EPUB and Kindle. Book excerpt: Recent years have witnessed a paradigm shift in the world of electronics. Researchers have not only continued to postpone the long dreaded end-of-Moore’s-law, but have also opened up a new world of possibilities with electronics. The future of electronics is widely anticipated to be dominated by wearable and implantable devices, the realization of which will be made possible by the discovery of new materials. Graphene and hexagonal boron nitride (hBN) are two such materials that have shown promising properties to make these devices possible. It has been shown that an energy bandgap can be opened in graphene by patterning it as a narrow ribbon, by applying an electric displacement field to a bilayer configuration, and by other means. The possibility of tuning the bandgap makes graphene an ideal channel material for future electronics. Similarly, hexagonal boron nitride (hBN) and its ribbon configurations have been shown to be excellent dielectric materials. In addition, the similarities in the atomic configurations of graphene and hBN allow them to conform extremely well to each other, achieving atomically smooth interfaces. Graphene devices on hBN substrates have been shown to have mobilities an order of magnitude larger than graphene devices fabricated on silicon dioxide. In addition to their outstanding electrical properties, graphene and hBN have been shown to have excellent thermal properties compared to their traditional counterparts (silicon and silicon dioxide, respectively). More specifically, these materials have been shown to have size dependent thermal properties which may be used to tune device performance. In this thesis, we study the thermal transport of three important classes of materials – graphene nanoribbons, hBN nanoribbons and graphene-hBN heterostructures using the phonon Boltzmann transport equation in a linearized framework. An exact solution of the Boltzmann transport equation is obtained ensuring that normal and umklapp phonon scattering processes are appropriately treated. In the first part of the thesis, we present a computational technique called method of automatic code differentiation to calculate sensitivities in nanoscale thermal transport simulations. Key phonon parameters like force constants, group velocities, the Gruneisen parameter, etc., which can be expressed as sensitivities or derivatives, are computed using this technique. The derivatives computed using this technique are exact and can be generalized to any order with minimal effort. This technique can be unintrusively integrated with existing first-principles simulation codes to obtain the sensitivities of parameters computed therein to chosen inputs. The next focus is to investigate the thermal properties of three main classes of materials – graphene nanoribbons, hBN nanoribbons,and graphene-hBN heterostructures. For nanoribbons, we consider ribbons of varying widths to investigate the transition of key thermal properties with width. The lattice structure of the ribbon structures considered is fully resolved. An efficient parallelization technique is developed to handle the large number of atoms in a unit cell. The thermal conductivity is obtained by an iterative solution of the linearized Boltzmann transport equation. For graphene and hBN ribbons, we find that the thermal conductivity increases with the ribbon width following a power-law trend. The rate of increase of thermal conductivity with width for hBN ribbons is found to be slower compared to graphene. Flexural phonons are found to contribute to the majority of heat conduction in both the materials. Frequency- and polarization-resolved transport is analyzed for ribbon of all widths. The thermal conductivity of single- and few-layer hexagonal boron nitride is also computed and compared with measured data. It is found that the thermal conductivity of hBN based nanostructures (single-layer, few-layer and ribbons) is around 6-8 times smaller than that for the corresponding graphene-based nanostructure. The effect of strain in both these materials is investigated. We find that the thermal conductivity of single-layer hBN is very sensitive to strain whereas graphene shows relatively less sensitivity for the same strains. Finally, thermal transport in graphene-hBN heterostructures is simulated. Two different structures are considered – single-layer graphene on an hBN substrate, and bilayer graphene on an hBN substrate. Substrates of different thickness are considered. Due to the weak interlayer coupling in these heterostructures, it is found that the phonon dispersion remains largely unchanged from the dispersions of the individual layers. The only difference in dispersion is noticed for flexural phonons, which are the only modes affected by interlayer coupling. The addition of an hBN layer underneath the graphene/bilayer graphene layer is found to drastically reduce the thermal conductivity of the heterostructures. This reduction is due to breakdown of the selection rule for flexural phonons which results in increased scattering channels for these phonons. The thermal conductivity gradually decreases, saturating to a bulk value with an increase in the number of hBN layers. The results presented in this thesis are expected to help guide the design of graphene/hBN based flexible electronics.
