Photoresponse of the PD.
(a) Photoresponse of the SLG-CNTF device to pulsed infrared irradiation at a frequency of 500 Hz. (b) Photoresponse of the CNTF/SLG device to pulsed infrared irradiation at a frequency of 5 kHz. (c) One normalized cycle measured at 5 kHz for estimating both rise (τr) and fall time (τf). (d) The normalized photocurrent versus switching frequency.
