Abstract

We have investigated the influence of the growth parameters during molecular beam epitaxy on the realizibility of diamond crystal structure Ge / α-Sn alloys and superlattices on Ge(001) substrates. The segregation behaviour of Sn during Ge overgrowth has been studied. We find that for growth temperatures higher than 300°C the incorporation rates are less than 0.005 ML-1. The low-energy electron ...
