Abstract

We have carried out full-scale pseudopotential calculations of the effect of zone-fol-ding on band structure, optical absorption and non-linear response function of semiconductor superlattices. To provide a complete picture of this phenomenon we chose to study GaAs-Gal-xAlxAs, Si-Si1-xGe and HgTe-CdTe superlattices which represent examples of the breakdown of the simple particle-in-a-box model because of Γ - X mixing, strain and relativistic effects, respectively.
