Influence of the electron-phonon interaction on electron transport in wurtzite GaN

A full-band electron transport calculation in wurtzite phase GaN based on an accurate model of electron-phonon interactions using a rigid pseudo-ion model is reported. The calculated deformation potentials are used to estimate the scattering rate in a cellular Monte Carlo (CMC) simulator. Longitudinal optical (LO)-like and transverse optical (TO)-like polar optical phonon scatterings are also employed in this work. The calculated velocity is lower than the previous works which used fixed deformation potentials.
