Abstract

We describe a simple model, based on counting of valence electrons at the interface, which can predict the surface reconstructions which provide optimal heteroepitaxial growth. Vertical photocurrent measurements on a series of ZnSe/GaAs heterostructures grown by molecular beam epitaxy, using various GaAs surface reconstructions, support the model predictions that surfaces which provide nearly equal number of the constituent atoms for interface bonds produce the highest quality interfaces.
