Nettet22. nov. 2024 · Similar to above, as the experiment from the green graph has the higher intensity, shouldn't the measured photocurrent be higher? Building on that, I don't … Nettet21. jun. 2003 · The intensity of light is the number of photons. Thus, intensity affects how many photoelectrons are emitted (remember one photon can only dislodge one electron - 'all or nothing'). This photoemission can only happen if each photon carries sufficient energy to knock electrons out. And this is dependent on frequency, since E = h f.

Nettet27. okt. 2015 · 1. Online, I found a graph of photocurrent vs. stopping voltage: And I can’t figure out how photocurrent and stopping voltage have such a relationship. Stopping voltage is proportional to maximum KE and photon frequency, but neither of those factors really affect photocurrent as long as the threshold is reached. I would appreciate … NettetFor 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 … keyboard cleaning goop
