Photoresponse (image) Science China Press Share Print E-Mail Caption This is the photoresponse of the nanoporous ZnO/ n-Si sample under the illumination of a 1064 nm laser pulse at varying energy levels. The symbols t1 and t2 represent the corresponding time of the transient voltage peaks. The inset shows the linear relationship between the time interval, i.e. (t2-t1), and the laser pulsed energy.
