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 … Webin photoelectric experiments we are always interested in finding two things one is counting the number of electrons coming out per second something that we discussed in our …
WebJun 21, 2003 · 2001. May 21, 2003. #1. If you look at a graph of photocurrent (emitted obviously during the photoelectric effect) VS stopping/retarding voltage, you'll find that … WebA graph is drawn between light intensity along x-axis and the photocurrent along y-axis. From the graph in Figure 7.9, it is evident that photocurrent – the number of electrons emitted per second – is directly proportional to the intensity of the incident light. Here, intensity of light means brightness. A bright light has more intensity ...
