Preferred Abstract (Original):
Three terminators have been tested, square root terminator,
quadreture terminator and linear terminator, it was found that the
linear terminator is the best, so it was used in calculating local
density of states (LDOS) and it's orbital decomposition, alloy average
density of states, and energygap for different anionconcentrations for InP lattice matched alloy. The results were compared with our previous calculations of (LDOS), and results from other methods. Energygap was compared with experimental measurements. A five orbital sp3s* per atom model was used in the tight-binding representation of the Hamiltonian.
