From: Bandgap-independent photoconductive detection in two-dimensional Sb2Te3
a Photocurrent of the detector under different bias at 0.167 THz, 0.270 THz and 0.340 THz. b Dependence of the photocurrent and the responsivity on the radiation intensity at 0.03 THz. c Time-resolved measurements at 0.167 THz with different bias voltage of 50 mV, 100 mV and 200 mV. d Polarization dependence of the detector at 0.167 THz. e Photoresponse of the detector under different bias voltage and modulation frequency. f Shows the rising edge and falling edge of the photoresponse in a single time-period.
