(a) Transient photocurrent at a frequency of 5000 Hz, (b) single normalized cycle of the photocurrent at a frequency of 500 Hz, and (c) frequency response of the photodetector at−0.5 V under modulated green-LED (530 nm) illumination. (d) Photocurrent density as a function of light intensity of the photodetector under green-LED (530 nm) illumination at different reversed bias voltages.
