Abstract

Using the perturbation method (Born approximation), a theoretical model has been developed to account for the EBIC intensities and contrasts likely to occur in an n-type polycrystalline semiconductor, as a function of the grain size. The influence of the minority charge carrier diffusion length and the primary electron beam energy have also been examined, respectively.
