High field electron and hole transport in wurtzite InN

A Monte Carlo technique has been used to investigate the steady-state, transient, and small-signal transport of electrons and holes in InN in high electric fields. The drift velocities and diffusion coefficients of electrons and holes are calculated using single-particle Monte Carlo method. The transient drift velocities of electrons and holes are evaluated from ensemble Monte Carlo simulations. The electron small-signal mobility is estimated. The threshold frequency of 550?GHz for the negative differential mobility (NDM) in InN is obtained.
