Demonstration of the effects of interface strain on band offsets in lattice-matched III-V semiconductor superlattices

Description

A first principles total energy self-consistent pseudopotential calculation is used to predict the band offset in the lattice-matched superlattice InAs/Al0.8Ga0.2As0.14Sb0.86. We find that inclusion of interface strain changes the character of the band offset from nominally type II to strongly type II. The predicted band offset at the minimum energy configuration is in excellent agreement with the value determined from infrared photoluminescence measurements
