This title provides a through explanation of the methodologies used for solving heat transfer problems in micro- and nanosystems. Written by one of the field's pioneers, this highly practical, focused resource integrates the existing body of traditional knowledge with the most recent breakthroughs to offer the reader a solid foundation as well as working technical skills. It includes the information needed to account for the size effect when designing and analysing systems at the nanometer scale, with coverage of statistical thermodynamics, quantum mechanics, thermal properties of molecules, kinetic theory, and micro/nanofluidics.It also covers: thermal transport in solid micro/nanostructures, electron and phonon scattering, size effects, quantum conductance, electronic band theory, tunneling, nonequilibrium heat conduction, and analysis of solid state devices such as thermoelectric refrigeration and optoelectronics; and, nanoscale thermal radiation and radiative properties of nanomaterials, radiation temperature and entropy, surface electromagnetic waves, and near-field radiation for energy conversion devices. In the nanoworld where the old axioms of thermal analysis may not apply, nano/microscale heat transfer is an essential research and learning source. Inside you will find: Statistical Thermodynamics and Kinetic Theory; Thermal Properties of Solids; Thermal Transport in Solids Micro/Nanostructures; Micro/Nanoscale Thermal Radiation; and, Radiative Properties of Nanomaterials.
