Luminescence signature of free exciton dissociation and liberated electron transfer across the junction of graphene/GaN hybrid structure

Large-area graphene grown on Cu foil with chemical vapor deposition was transferred onto intentionally undoped GaN epilayer to form a graphene/GaN Schottky junction. Optical spectroscopic techniques including steady-state and time-resolved photoluminescence (PL) were employed to investigate the elec...
