What is Band-Inverted Heterojunctions Overview about?

This document summarizes electronic properties of heterojunctions between semiconductors with inverted energy bands. The key points are: 1) These "band-inverted" heterojunctions contain massless, spin-nondegenerate electron states localized at the interface that are independent of the band profile. 2) The presence of these interface states is ensured by a special symmetry (called supersymmetry) of the effective Hamiltonian for such systems. 3) Other material structures that also have this supersymmetri
