This book was released on 2010 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon's chemical stability, high natural abundance (as the second most common element in the earth's crust), mechanical stiffness, and semiconducting behavior have made it the subject of extensive scientific investigation and the material of choice for both the microelectronics and microelectromechanical device industries. The success of Moore's Law that demands continual size reduction has directed it to a central place in emerging nanoscience and nanotechnology as well. Crystalline nanowires (NWs) are one nanostructured form that silicon may take that has sparked significant interest as they can exhibit considerable confinement effects and high surface-to-volume ratios, but may be interfaced simply along one direction for the determination of material properties and implementation into new technologies. The expense and difficulty involved in the creation of semiconductor nanowires using the "top down" fabrication techniques of the microelectronics industry has promoted an explosion of chemical synthetic "bottom up" techniques to produce high quality crystalline nanowires in large quanitities. Nevertheless, bottom up synthesized Si NWs retain a new set of challenges for their successful integration into reliable, high-performance devices, which is hindered by an incomplete understanding of the factors controlling their material properties. The first chapter of this dissertation introduces the motivation for studying semiconductor NWs and the benefits of limiting the scope to silicon alone. A brief survey of the current understanding of thermal conductivity in silicon nanowires provides prime examples of how confinement effects and surface morphology may dramatically alter nanowire properties from their bulk crystal counterparts. The particular challenges to bottom up silicon nanowire device integration and characterization are noted, especially related to Si nanowires that are grown epitaxially on crystal silicon substrates, and Raman spectroscopy is introduced as a promising optical characterization and metrology tool for semiconductor nanowire based devices. Chapter two describes the vapor-liquid-solid (VLS) mechanism for the synthesis of very high quality, single-crystal silicon nanowires using Au and Pt catalyst nanoparticles. A new technique is presented for the simplified synthesis of branched silicon nanowires based on the migration of Au catalyst during an hydrogen anneal intermediate between growth stages, and the faceting behavior at synthetic stages is revealed by the analysis of electron microscope images. Synthesis of solid and porous Si nanowires based on Ag mediated electrochemical silicon etching is described as well. The third chapter specifies new processing techniques developed with future device integration of epitaxially VLS-grown Si nanowires in mind. Epitaxially bridging nanowires are shown to provide an excellent platform for single-wire electrical and mechanical property measurements. Galvanic displacement through block copolymer micelle/homopolymer surface templates is demonstrated as a means to deposit catalyst nanoparticles with controlled sizes and areal densities in a variety of geometries and with registration to photolithographic patterns. Ex situ boron doping by the direct hydrogen reduction of boron tribromide is shown to achieve active concentrations exceeding 1019 cm-3 with high axial uniformity, while avoiding the adverse impact on nanowire morphology that is often observed with in situ boron doping of silicon nanowires. Chapter four describes the characteristics of Raman spectroscopy that are relevant to studying individual semiconductor nanowires. Careful spectral measurements show that the anharmonic dependence of Raman spectra on temperature for individual Si nanowires remains unchanged from the bulk crystal for diameters down to 30 nm, regardless of surface morphology. Using this result, a new technique for measuring the thermal conductivity of individual semiconductor nanowires is then outlined based on Raman thermal mapping of individual cantilevered nanowires. Finally, the dissertation is concluded with suggestions for possible future experiments. One avenue is to probe more deeply the morphology of faceted silicon nanowires and nanotrees and its impact on their transport physics. Another possible route for further study would be to explore new characterization and metrological applications of Raman spectrocopy for semiconductor nanowires.

Download or read book Fabrication and Characterization of High Performance Silicon Nanowire Field Effect Transistors written by Muhammad Maksudur Rahman and published by . This book was released on 2011 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quasi one-dimensional (1-D) field-effect transistors (FET), such as Si nanowire FETs (Si NW-FETs), have shown promise for more aggressive channel length scaling, better electrostatic gate control, higher integration densities and low-power applications. At the same time, an accurate bench-marking of their performance remains a challenging task due to difficulties in definition of the exact channel length, gate capacitance and transconductance. In 1-D Si FETs, one also often observes a significant degradation of their mobility and on/off ratio. The goal of this study is to implement the idea of the FET performance enhancement while simultaneously performing a more rigorous data extraction. To achieve these goals, we fabricated dual-gate undoped Si NW-FETs with various NW diameters The Si NWs are grown by Au-catalyzed vapor-transport For our top-gate NW-FET, the subthreshold swing was determined to be 85-90 mV/decade, whereas the best subthreshold swings for Si NW-FETs until now were ~135-140 mV/decade. We achieved a ON/OFF current ratio of 10 7 due to improved electrostatic control and electron transport conditions inside the channel. This is on the higher end of any ON/OFF ratios thus far reported for NW FETs The hole mobility in our NW-FETs was around 250.400 cm[superscript 2] /Vs, according to different extraction procedures. In our mobility calculations we included the NW silicidation effect, which reduces the effective channel length. We calculated the top gate capacitance using Technology Computer Aided Design (TCAD) Sentaurus simulator, which gives more accurate value of capacitance of the NW over any analytical formulas. Thus we fabricate and rigorously study Si NW.s intrinsic properties which are very important for digital logic circuit application. In the second part of the study, we carried out simulation of Si NW FET devices to shed light on the carrier transport behavior that also explains experimental data.

This book was released on 2010 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon nanowires, silicon nanorods, and magnetic nanocrystals have shown interesting size, shape, mechanical, electronic, and/or magnetic properties and many have proposed their use in exciting applications. However, before these materials can be applied, it is critical to fully understand their properties and how to synthesize them economically and reproducibly. Silicon nanowires were synthesized in high boiling point ambient pressure solvents using gold and bismuth nanocrystals seeds and trisilane as the silicon precursor. Reactions temperatures as low as 410°C were used to promote the solution-liquid-solid (SLS) growth of silicon nanowires. The silicon nanowires synthesis was optimized to produce 5 mg of silicon nanowires with average diameters of 30 nm and lengths exceeding 2 [mu]m by adjusting the silicon to gold ratio in the injection mixture and reaction temperature. Silicon nanorods were synthesized using a solution-based arrested-SLS growth approach where gold seeds, trisilane, and a dodecylamine were vital to the success. Dodecylamine was found to prevent gold seed coalescence at high temperatures -- creating small diameter rods -- and bond to the crystalline silicon surface -- preventing silicon nanorod aggregation. Furthermore, an etching strategy was developed using an emulsion of aqua regia and chloroform to remove the gold seeds from the silicon nanorods tip. A thin silicon shell surrounding the gold seed of the silicon nanorod was subsequently observed. Multifunctional colloidal core-shell nanoparticles of iron platinum or iron oxide encapsulated in fluorescent dye doped silica shells were also synthesized. The as-prepared magnetic nanocrystals are initially hydrophobic and were coated with a uniform silica shell using a microemulsion approach. These colloidal heterostructures have the potential to be used as dual-purpose tags, exhibiting a fluorescent signal that could be combined with enhanced magnetic resonance imaging contrast. Compositionally-ordered, single domain, antiferromagnetic L12 FePt3 and ferromagnetic L10 FePt nanocrystals were synthesized by coating colloidally-grown Pt-rich or stoichiometricly equal Fe-Pt nanocrystals with thermally-stable SiO2 and annealing at high temperature. Without the silica coating, the nanocrystals transform predominately into the L10 FePt phase due to interparticle diffusion of Fe and Pt atoms. Magnetization measurements of the L12 FePt3 nanocrystals revealed two antiferromagnetic transitions near the bulk Neél temperatures of 100K and 160K. Combining L12 FePt3 nanocrystals with L10 FePt nanocrystals was found to produce a constriction in field-dependent magnetization loops that has previously been observed near zero applied field in ensemble measurements of single domain silica-coated L10 FePt nanocrystals. Dipole interactions between FePt@SiO2 nanoparticles with varying SiO2 shell thickness was also explored.
