LCAO Interpolation Method with Nonorthogonal Orbitals
Most applications of the Slater-Koster tight-binding interpolation method1 utilize basis functions formed from orthogonalized atomic orbitals. We shall refer to this scheme as the LCOAO method or the linear-combination-of-orthogonalized-atomic-orbitals method. In such applications, the independent tight-binding energy integrals that occur in the Hamiltonian matrix are treated as disposable parameters which are chosen to fit the results of accurate band calculations at symmetry points in the Brillouin zone.
