Abstract
A monolithic integrated full-wave bridge rectifier consisted of horizontal Schottky-barrier diodes (SBD) is prepared based on 100 nm ultra-thin β-Ga2O3 and demonstrated the solar-blind UV (SUV) light-modulated characteristics. Under SUV light illumination, the rectifier has the excellent full-wave rectification characteristics for the AC input signals of 5, 12, and 24 V with different frequencies. Further, experimental results confirmed the feasibility of continuously tuning the rectified output through SUV light-encoding. This work provides valuable insights for the development of optically programmable Ga2O3 AC-DC converters. -
