Abstract

Gallium Nitride is a key material for the future of high-power electronics. Such devices are characterized by very large electric current which in turn generates enormous amounts of heat. Removal of this heat from the device depends crucially on the thermal conductivity of GaN and thermal conductance through its interface with other components of the device. The goal of this project is to determine the thermal transport properties of GaN both internally and across a resistant grain boundary. In this work, we are determined these properties using Non-Equilibrium Molecular Dynamics technique via community code LAMMPS. Results of the simulations are compared to experimental measurements and ab-initio caculations.
