Characterization of the fabricated photodetector. (a) Schematics of the measurement set-up. (b) The measured I–V characteristics of the device (green circle: dark state, pink square: Plight = 22.5 μW/cm2). (c) The dynamic optoelectronic response of the fabricated photo-detector (upper panel), and the intensity of incident light (gray solid star: Plight = 22.5 μW/cm2). (d) The calculated sensitivity (S) of the device with respect to various Plight (inset: measured S changes by increasing and decreasing Plight). e) The calculated photo-responsivity (R) and photo-detectivity (D*) of the device with respect to various Plight . f) The dynamic response of the photodetector for Plight = 22.5 μW/cm2; rise time (τr) and decay time (τd) were 0.329 s and 1.21 s, respectively.
