Electronic Structure of GaAs and AlAs using a Hamiltonian Tight-Binding sp3s∗

We calculate the electronic states in volume for GaAs and AlAs in Zinc-Blenda structure using the Tight-Binding (TB) method. The TB Hamiltonian was constructed using a base of s, p and s∗ orbitals. Thes∗ orbitals represent excited states with equal symmetry as the s orbitals. Carrying out the numeri...
