A Method for Calculating Electronic Structure of Semiconductor Superlattices: Perturbation
A similarity transformation of the superlattice Hamiltonian is presented. The transformed Hamiltonian includes two parts. One that describes the average crystal, and the other the interaction between average crystal states. This interaction is small and is treated as a perturbation. The method is applied to GaSb/InAs (100) superlattice, and its band structure is analyzed.
