Abstract
The effect of nonequilibrium longitudinal optical (LO) phonons on electron transport in wurtzite InN in high electric fields is studied by Monte Carlo simulations. The novel and efficient single-particle Monte Carlo method for a self-consistent simulation of nonequilibrium electron and phonon systems is developed. The effect of nonequilibrium LO phonons on electron drift velocity, valley population, and small-signal ac mobility in InN is investigated. It is found that the effect of nonequilibrium LO phonons on electron transport characteristics in InN becomes pronounced when electron density exceeds 1017 cm−3.
