DOI: 10.1063/1.5044383
Abstract: We show that the often observed efficiency droop in AlGaN quantum well heterostructures is an internal carrier loss process, analogous to the InGaN system. We attribute this loss process to Auger recombination, with C = 2.3 × 10−30 cm6 s−1;… read more here.

DOI: 10.1088/1361-6463/ac4185
Abstract: Self-assembled AlGaN nanowires (NWs) are regarded as promising structures in the pursuit of ultraviolet photodetectors (UV PDs). However, AlGaN NW-based PDs currently suffer from degraded performance partially due to the existence of outstanding surface-related defects/traps… read more here.

DOI: 10.1134/s1063782618050056
Abstract: We report on fabrication and studies of composite heterostuctures consisting of an Al0.55Ga0.45N/Al0.8Ga0.2N quantum well and surface Al nanoislands, grown by plasma-assisted molecularbeam epitaxy on c-sapphire substrates. The influence of a substrate temperature varied between… read more here.
