摘要：
The magnetoresistivity of a two dimensional electron system confined in a wurtzite Al0.22Ga0.78N/GaN heterostructure has been reproduced using a theoretical model based on a modified semiclassical theory. When an external magnetic field is applied, nodes appear on the beating pattern Subnikov-de Haas oscillations due to carriers with different spin orientations. The analysis of the magnetoresistivity experimental data with the model led us to know accurately the value of the spin-orbit coupling material parameters. (C) 2013 AIP Publishing LLC.
