Thermal conductivity of fivefold twinned silicon-germanium heteronanowires

Abstract

The thermal transport properties of five-fold twinned (5FT) germanium–silicon (Ge–Si) heteronanowires (h-NWs) with varying cross-sectional areas, germanium (Ge) domain ratios and heterostructural patterns are investigated using homogeneous nonequilibrium molecular dynamics (HNEMD) simulations.
