Anomalous Thermal Transport in Nanostructures

Abstract

Thermal transport in nanoscale structures has attracted an increasing attention in the past two decades. Here we give a brief overview of the recent developments in experimental and theoretical studies of heat transport in nanomaterials such as nanotubes and nanowires. In particular, we will demonstrate that the phonons in nanotubes and nanowires transport superdiffusively, which leads to a length-dependent thermal conductivity. In other words, heat conduction in low-dimensional nanostructures does not obey Fourier's law. © 2013 Wiley-VCH Verlag GmbH & Co. KGaA.
