Abstract :
We report on magnetotransport characterization of grating-gate GaN/AlGaN-based THz detectors. Results of our experiments show that depending on the geometry of a grating, 2D electron channel may be divided into gated and ungated regions with different concentrations and mobilities of the carriers.
