Monte Carlo Analysis of Effect of Alloy Scattering on Electron Transport in Wurtzite Zn_1-xMg_xO

Abstract:

Steady-state and transient electron characteristics of wurtzite Zn_1xMg_xO are studied in detail. An ensemble Monte Carlo model is established considering alloy scattering. From the steady-state characteristics, it is found that alloy scattering makes the drift velocity decrease at different electric fields. For 10% Mg, the transient peak drift velocity decreases from 2.48×10⁷ cm/s to 2.13×10⁷ cm/s at 2000 kV/cm. While for 20% Mg, a higher electric field is needed for the onset of the overshoot, which corresponds to the larger peak electric field in the steady-state velocity-field characteristics.
