Abstract

Magneto-transport measurements have been carried out on a Si modulation-doped Al_0.22Ga_0.78N/GaN heterostructure in a temperature range between 1.5 and 25 K under magnetic field up to 10 T. Striking beating patterns in magnetoresistance vs magnetic field are observed in the vicinity of a specific temperature. Theoretical simulation is performed and the comparison between numerical simulations and the experimental data reveals that the beating patterns are due to the interference of the magneto-intersubband scattering and the SdH oscillator of first subband.
