Abstract

In order to understand the process of band-offset modification by the introduction of interlayers at semiconductor heterojunctions, the authors performed self-consistent ab initio pseudopotential calculations on the Si/Ge interface with In and Sb interlayers. The results of the calculations show a substantial reduction in the valence band offset with the Sb interlayer compared with no interlayer but no change when In is introduced. They suggest a possible reason for these different results
