Modeling self-heating effects in 10nm channel length nanowire transistors

Abstract

Modern technology has enabled the fabrication of materials with characteristic dimensions of a few nanometers. Examples are superlattices, nanowires and quantum dots. Thermal transport in these low-dimensional nanostructures is important for next-generation microelectronic cooling techniques, novel solid-state energy conversion devices, and micro-nanoscale sensors. Thermal transport caused by lattice vibrations or phonons in nanostructures is very complicated due to the comparable phonon mean-free path, phonon wavelength, and the characteristic size of the nanostructures.
