GaN epilayers are grown on (111) oriented single crystal diamond substrate by ammonia-source molecular beam epitaxy. Each step of the growth is monitored in situ by reflection high energy electron diffraction. It is found that a two-dimensional epitaxial w ...
High mobility Al0.28Ga0.72N/GaN two-dimensional electron gas (2DEG) is achieved on ( 111) oriented single crystal diamond substrate. The surface morphology of the epilayer is free of cracks thanks to the use of an AlN interlayer for strain relaxation. The ...
