Size-dependent thermal conductivity of nanoscale semiconducting systems
arXiv:cond-mat/0603233 · doi:10.1103/PhysRevB.73.153303
Abstract
We study the size dependence of thermal conductivity in nanoscale semiconducting systems. An analytical formula including the surface scattering and the size confinement effects of phonon transport is derived. The theoretical formula gives good agreements with the existing experimental data for Si and GaAs nanowires and thin films.
