A new method is proposed for determining the bulk minoritycarrier diffusion length and surface recombination velocity. Moreover, the electron-beam-induced current (EBIC) profile in which the p-n junction is parallel to the electron beam is obtained using SEM. A simple model is used to calculate the EBIC profile and to fit with the experiment data, then the diffusion length and surface recombination velocity are obtained.
