Abstract: The high-field electron transport properties of ZnMgO/ZnO heterostructures considering multisubband conduction were systematically investigated with an ensemble Monte Carlo program developed by us. Electronic band structures were obtained by first-principles calculations using density functional theory, which provides more accurate parameters to calculate the electronic states and transport characteristics of 2-D electron gas. Wave functions and energy levels describing the subband structure were achieved to determine the 2-D scattering rates by solving the Schro&#x0308;dinger and Poisson equations self-consistently. The highest electron mobility gained at room temperature was approximately 4.23&#x00D7;102 cm2 /Vs. The negative differential mobility was observed with a threshold electric field of approximately 80 kV/cm. The peak drift velocity of the Zn<sub>0.694</sub>Mg<sub>0.306</sub>O/ZnO heterostructure at 200 KV was about 2.011 &#x00D7; 108 cm/s. This paper benefits the development of high-performance ZnMgO/ZnO heterostructure devices.
