Abstract

We report results of a self-consistent pseudopotential study within the local density formalism of the ultrathin (GaP) n (InP) n (n = 1, 2, 3) superlattices. The trend in the band structure of the superlattices with increasing n has been investigated. The lattice mismatch effect is observed in the electronic structure and the equilibrium interface geometry is analysed by using the total energy and Hellmann-Feynman's force.
