Abstract

The electronic structure of strained (001) HgTe-CdTe superlattices is studied for (2, 2) ⩽ (n, m) ⩽ (20, 20), where n(m) is the number of monolayers of HgTe (CdTe). The effects of the valence band offset (VBO) are also considered. The calculation is based on an empirical tight binding (ETB) model together with a surface Green function matching analysis.
