Determination of photoelectric current by voltage between anode and cathode, intensity and frequency of light
View through CrossRef
Based on the Fermi-Dirac distribution, a typical numerical method to calculate photoelectric current by voltage between anode and cathode in vacuum is developed. The results of simulations agree very well with the observed curves consisting of photoelectric current and voltage. Then, the contribution of intensity of incident light to photoelectric current is obtained mathematically. Finally, the wavelength of incident light is related to photoelectric current theoretically. Hence, photoelectric current can be predicted.
