Description
Summary:Si-doped β-Ga2O3 films are fabricated through metal-organic chemical vapor deposition (MOCVD).Solar-blind ultraviolet (UV) photodetector (PD) based on the films is fabricated by standard photolithography,and the photodetection properties are investigated.The results show that the photocurrent increases to 11.2 mA under 200 μW·cm-2254 nm illumination and ±20 V bias,leading to photo-responsivity as high as 788 A·W-1.The Si-doped β-Ga2O3-based PD is promised to perform solar-blind photodetection with high performance.
