Study of electron transport properties for wurtzite GaN and ZnO with full band Monte Carlo simulation

We present the first calculated results of electron transport properties of the wurtzite GaN and ZnO with the full band Monte Carlo simulations.The band structure data being used in the simulations are based on the empirical pseudopotential method.The characteristics of drift velocity field and average energy field for both materials are obtained from Monte Carlo calculations,and electron mobility also are obtained.The comparison among the results of both materials,as well as the Monte Carlo results of GaAs reported by other authors have been made.
