Thermal and Thermoelectric Transport in Nanostructures and Low-Dimensional Systems

摘要

Significant progress has been made in recent studies of thermal andthermoelectric transport phenomena in nanostructures and low-dimensionalsystems. This article reviews several intriguing quantum and classical sizeeffects on thermal and thermoelectric properties that have been predicted bytheoretical calculations or observed in experiments. Attention is focused onthe Casimir limit in phonon boundary scattering and the effect of phononconfinement on the lattice thermal conductivity of semiconductor nanowires(NWs) and nanomeshes; the effects of thickness, lateral size, and interfaceinteraction on the lattice thermal conductivity of carbon nanotubes (CNTs) andgraphene; and the phonon-drag thermopower and quantum size effects on thethermoelectric power factor in semiconductor NWs. Further experimental andtheoretical investigations are suggested for better understanding of some ofthese nanoscale transport phenomena.
