The full band Monte Carlo method is used to explore steady-state electron transport and transient electron transport in ZnO. For the steady-state electron transport, the velocity-field characteristics, average energy-field characteristics and electron distributions in energy are presented. An important feature of the velocity-field characteristics is a differential negative resistance effect in steady state electron drift velocity. For the transient electron transport, velocity-distance characteristics and transit time-distance characteristics are reported. In velocity-distance characteristics, the effect of velocity overshoot is found. Relaxation time of electron transfer from lower valleys to higher valleys causes the overshoot effect.
