We present a new tight binding view of the heterojunction band offsets. The model considers the nonorthogonality of the sp 3 set of orbitals of adjacent atoms and spin-orbit coupling and uses the Hartre-Fock atomic energies and interacting matrix element, obtained by fitting bulk band structures of

We present a new tight binding view of band offsets in group II-VI based heterojunctions. The model considers the nonorthogonality of sp 3 set of orbitals of adjacent atoms and the interaction of bonding and antibonding states at high symmetry points in calculating the valence band energies at 0 K a
