Photoresponse behavior of the photodetector. The I–V characteristics under different 405 nm laser power densities (a) and under different incident wavelengths of 5 mW/cm2 (b). (c) The time-resolved photoresponse excited by the periodic on/off switching of incident light. (d) The extracted R (black sphere) as a function of laser power densities. The applied voltage for (c–d) is 1 V
