Fig. 3 — a Real-time current (I_DS) of the device to various light stimuli, where a 532 nm CW laser with power densities of 50 μW/cm² and 5 W/cm² is employed to emulate the soft and bright light irradiation, respectively. b Power-dependent real-time I_DS on a semi-log scale, ranging from 50 μW/cm² to 5 W/cm². c Normalized real-time I_DS of the device under bright light irradiation (power density: 60 mW/cm²) at wavelengths between 300 and 1000 nm. All above the photo-responses are measured under zero bias voltage
