Low dark current and internal gain mechanism of GaN …

The photodetector with a high UV-to-visible rejection ratio of up to 1 × 10 5 exhibits a low dark current of <2 pA at room temperature under 10 V bias. The photo-responsivity of the photodetector gradually increases as a function of applied bias, resulting in a photodetector quantum efficiency exceeding 100% at above medium bias.
