Photoresponse of the NIRPD.
(a) Photoresponse of the AuNPs@graphene/CH3-SiNWs array NIRPD under light illumination with increasing intensities from 0.81 to 174 μW/cm2; (b) The fitting of the relationship between the photocurrent and light intensity. The light wavelength was 850 nm; (c) Photoresponse of the NIRPD to pulsed IR light irradiation (850 nm) at different frequencies; (d) The relative balance (Imax − Imin)/Imax versus switching frequency; (e) A single normalized cycle measured at 2200 Hz for estimating both response time (τr) and recovery time (τf).
