Klappentext A unique focus on experimental techniques for the characterization of thermal transport in micro/nanoscale materialsIn the rapidly evolving field of nanotechnology, it ultimately comes down to experiments and measurement techniques to obtain and validate data on the thermophysical properties of nanoscale and nanostructured materials for various engineering applications. Experimental Micro/Nanoscale Thermal Transport details techniques developed in the author's own laboratory that boast significantly reduced experimental time, superior signal-to-noise ratio, and high-accuracy measurement results.The book walks readers through the entire process of setting up and implementing advanced new technologies, including physical principles and data analysis for measuring the thermal conductivity/diffusivity of micro/nanoscale films and wires, while giving clear instructions on how to conduct experiments, assess uncertainties, and interpret physical results.Highlights of Experimental Micro/Nanoscale Thermal Transport include:* The introduction of the superior optical heating and electrical thermal sensing (OHETS) technique, along with other techniques in the frequency domain* Highly efficient methods for accurate transient measurement in the time domain, such as transient electro-thermal (TET), transient photo-electro-thermal (TPET), and pulsed laser-assisted-thermal relaxation (PLTR) techniques* Measurement of full-spectrum thermophysical properties using the generalized electro-thermal (GET) technique, one of the most advanced technologies available* Novel temperature differential measurement using Raman spectroscopy to achieve direct evaluation of the local thermal resistance at material interfaceThe first of its kind to focus on thermal characterization of the thermophysical properties of micro/nanoscale materials, this book will help researchers in material design and characterization tackle challenging thermal transport problems, quickly establish their own measurement techniques, and gain invaluable insight into experimental design. "Experimentalists measuring thermal transport properties of micro-or nanoscale materials will definitely find this book well worth their time." (IEEE Electrical Insulation Magazine , 1 September 2013 Zusammenfassung This book covers the new technologies on micro/nanoscale thermal characterization developed in the Micro/Nanoscale Thermal Science Laboratory led by Dr. Xinwei Wang.
