Time-dependent response of the detector at a series of bias voltage. a Multi-cycle time-dependent photocurrent of the detector at 0 V bias, under 185 nm illumination of 295.4 μW/cm2. The current has been taken as an absolute value, same as below. b Single time-dependent photocurrent at 0 V bias. The rise time and fall time are 19.3 and 1.8 s, respectively. Here, the range from Imin to 90% of Imax is defined as rise time, and the range from Imax to 10% of Imax is defined as fall time. c Time-dependent photocurrent at a series of bias voltage under the fixed 185 nm light power density of 295.4 μW/cm2. d Dependence of photocurrent and rise time on bias voltage. Red zone indicates the range of rise time, under the bias voltage from − 2 V to − 8 V
