Abstract :
We study the sensitivity of the steady-state electron transport that occurs within bulk wurtzite zinc oxide to variations in the non-parabolicity coefficient. An ensemble semi-classical three-valley Monte Carlo simulation approach is used for the purposes of this analysis. We find that for non-parabolicity coefficient selections beyond 0.4 eV −1, very few transitions to the upper energy conduction band valleys occur. This sensitivity to variations in the non-parabolicity coefficient has implications in terms of the form of the resultant velocity-field characteristics.
