Photocurrent formula
WebFor photocurrent autocorrelation spectroscopy, a pump laser pulse is focused on the nanowire (Figure 13.2).This exciting pulse needs to be intense enough to generate a photocurrent in saturation (e.g., because of bleaching due to state filling (Ahn et al., 2012; Li et al., 2014; Lo et al., 2012)).A second probe laser pulse hits the nanowire at the same … WebThe responsivity (or radiant sensitivity) of a photodiode or some other kind of photodetector is the ratio of generated photocurrent and incident (or sometimes absorbed) optical power (neglecting noise influences), determined in the linear region of response. In the case of photodiodes, the responsivity is typically highest in a wavelength ...
