This book was released on 2016 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since its introduction, Scanning Thermal Microscopy (SThM) has been widely used to measure surface temperature and thermal properties of nano-scale materials and structures with high spatial resolution. However, discrepancy exits between the temperature read by the SThM probe and the actual temperature of sample measured. In addition, the temperature of the measured sample can be affected by the presence of the SThM probe. In this thesis work, we used Ansys Fluent to develop a SThM model to establish calibration between the temperature read by the SThM probe and the actual temperature of measurement. The effects of the probe on the temperature of sample is also quantified. We use Bayesian inference to calibrate the unknown thermal conductivities of the polymer (substrate). This model is validated by comparing its predictions with experiment observations. We also quantify the uncertainties in the Quantity of Interest (QoI), the probe tip temperature, due to the uncertainty in the simulation input parameters. This is accomplished by using a generalized polynomial chaos (gPC) formalism. A response surface relating the QoI to model inputs is constructed through stochastic collocation. A Smolyak sparse grid is used to reduce the computation expense. The response surface is sampled based on the PDFs of the input parameters to obtain the PDF of the QoI. We find the uncertainty in the cross-plane thermal conductivity of the liquid polymer and the diameter of the probe tip have large contributions to the overall uncertainty in the QoI.

Book Synopsis Thermometry at the Nanoscale by : Luís Dias Carlos
Download or read book Thermometry at the Nanoscale written by Luís Dias Carlos and published by Royal Society of Chemistry. This book was released on 2015-10-02 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in technologies have created a need for sensing and measuring temperature at the nanoscale. This challenge requires new approaches and new techniques, since conventional thermometry is not valid at this scale. Thermometry at the Nanoscale covers the fundamentals of the subject, followed by individual chapters on luminescence-based and non-luminescence based thermometry techniques, and finally specific chapters on different applications of nanothermometry. The fundamental topics covered include a review of temperature measurement, the meaning of temperature on the nanoscale and heat propagation at the nanoscale. Luminescence-based techniques covered include quantum dots thermometry; lanthanide phosphors thermometry; organic dyes thermometry; polymer-based thermometry and organic-inorganic hybrids thermometry. Non-luminescence based thermometry techniques include scanning thermal microscopy; near-field thermometry and nanotubes thermometry. The range of applications of nanothermometry discussed includes thermometry inside a cell; microelectronics and micro/nanonofluidics. This is the first book to cover the whole subject of thermometry at the nanoscale with specialists in each particular technique discussing in detail the recent achievements and limitations as well as future trends and technological possibilities. The book will appeal to researchers from materials science, physical chemistry, analytical chemistry and biological sciences working on the development of new materials, materials characterisation/analysis and their applications.

Available in PDF, EPUB and Kindle. Book excerpt: One of the main challenges nowadays concerning nanostructured materials is the understanding of the heat transfer mechanisms, which are of the utmost relevance for many specific applications. There are different methods to characterize thermal conductivity at the nanoscale and in films, but in most cases, metrology, good resolution, fast time acquisition, and sample preparation are the issues. In this chapter, we will discuss one of the most fascinating techniques used for thermal characterization, the scanning thermal microscopy (SThM), which can provide simultaneously topographic and thermal information of the samples under study with nanometer resolution and with virtually no sample preparation needed. This method is based on using a nanothermometer, which can also be used as heater element, integrated into an atomic force microscope (AFM) cantilever. The chapter will start with a historical introduction of the technique, followed by the different kinds of probes and operation modes that can be used. Then, some of the equations and heating models used to extract the thermal conductivity from these measurements will be briefly discussed. Finally, different examples of actual measurements performed on films will be shown. Most of these results deal with thermoelectric thin films, where the thermal conductivity characterization is one of the most important parameters to optimize their performance for real applications.

Book Synopsis Characterizing Thermal and Chemical Properties of Materials at the Nanoscale Using Scanning Probe Microscopy by : Ranjan Grover
Download or read book Characterizing Thermal and Chemical Properties of Materials at the Nanoscale Using Scanning Probe Microscopy written by Ranjan Grover and published by . This book was released on 2006 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current magnetic data storage technology is encountering certain fundamental limitations that present roadblocks to its scalability to areal densities of 1 Tbit/in2̂ and beyond. Next generation magnetic storage technology is expected to use optical near field techniques to heat the magnetic film locally to write data bits. This requires experimental measurement of thermal conductivity of materials with sub--100 nm resolution. This is essential for the tailoring of the thin film stack to optimize the heat transfer of the process. This can be accomplished with a simple modification to a traditional atomic force microscopy (AFM) system. The modification requires the deposition of a thin metal film on the AFM cantilever thus creating a bimetallic cantilever. The curvature of a bimetallic cantilever is sensitive to temperature. Another modification is the use of a heating laser to raise the temperature of the cantilever so that when it scans across a sample with areas of varying thermal conductivity the bimetallic deformation of the heated cantilever is altered. The resulting system is sensitive to local variations in thermal conductivity with nanoscale resolution. Nanoscale thermal conductivity measurements can then be used to optimize the heat transfer properties of the materials used in a heat assisted magnetic recording system. AFM technology can also play a key role in the development of next generation solid-state chemical sensors. An AFM can be used to measure the workfunction of a material with near atomic resolution thus enabling the study of chemical reactions with high spatial resolution. Since chemical sensors typically use a chemical reaction at their front end to monitor the prescience of a gas, an AFM system can thus be used to understand and optimize the properties of the chemical reaction by monitoring the local workfunction. In thisthesis, I explain the use of atomic force microscopy in measuring thermal and chemical properties of materials with applications towards the magnetic storage industry and chemical sensing.
