Abstract
Core–shell heterostructures have attracted extensive attention in the photoelectric field because of their improved optoelectrical properties. In this study, we report a novel self-powered ultraviolet (UV) photodetector based on In2O3/InN nanorods (NRs) core-shell heterostructure developed on the corrugated V-grooved Si (100) substrate. Under 365 nm UV light the hybrid heterostructure demonstrates remarkable photo-to-dark current ratio, high detectivity (64.85 A/W), responsivity (8.5 × 1012 Jones) excellent external quantum efficiency (9.15 × 103 %) and fast rising/falling times in a self-driven mode (0 V). This remarkable photoelectric detection capability is attributed to the strong absorption and abundant trapping of UV light by the multiple scattering of V-grooved texture and formation type-II heterojunction between the In2O3 and InN NRs core-shell structure resulting self-power mode, which enable notable charge separation and fast electron transfer. These accomplishments set the stage for future optoelectronic applications of III-nitride based core-shell heterostructure UV photodetectors that are self-powered.
