Abstract
The authors have carried out pseudopotential calculations concerning the electronic structure of (100) GaAs-Ga0.8Al0.2As superlattice with period approximately (70+70) AA. They recover the states reported earlier in optical experiments and in envelope function calculations. They also find new well localised states lying close to the top of the confining barriers. These states have large amplitudes in the confining alloy layers.Keywords
