Abstract

This study aims to investigate the effect of electrode spacing on the performance of amorphous gallium oxide photodetectors. Firstly, we prepared a series of amorphous gallium oxide photodetector samples with electrode spacings of 80 µm, 100 µm, and 120 µm. Then, we tested the photoelectric performance of these samples. We found that the electrode spacing has a significant effect on the responsivity of the photodetectors. Due to the reduction of the carrier transmission distance, smaller electrode spacing can effectively improve the responsivity of the a-Ga₂O₃ photodetector, which reaches 0.096 A/W under 30 V, 255 nm illumination. This study provides a reference for the optimal design of the electrodes of amorphous Ga₂O₃ photodetectors.
