Quantitative analysis of electron-beam-induced current profiles across p-n junctions in GaAs/Al0.4Ga0.6As heterostructures

We propose a method for the quantitative evaluation of electron-beam-induced current profiles measured in normal-collector geometry across p-n junctions in GaAs/Al0.4Ga0.6As heterostructures. We obtain a theoretical expression, valid for all distances from the junction, and which takes into account the spatial extension of the electron-hole pairs generation. From the comparison of calculated with experimental profiles, we evaluate the minority carrier diffusion length and to some extent the surface recombination velocity.
