Abstract

We apply Klemens' second-order perturbation theory to investigate thermal conductivity in wurtzite GaN films. Specifically, the effect of edge, screw, and mixed types of dislocations and their orientation with respect to the temperature gradient on the thermal conductivity values is analyzed. Using typical impurity profiles for GaN films, we study the relative contribution of different impurities into thermal resistance.
