Abstract

Assuming an s-orbital basis the extended Hückel eigenvalues and eigenvectors have been calculated for a two dimensional model of an edge dislocation. Finite configurations have been considered as well as infinite arrays of dislocations. The results show localized states with energies above the band limit of the corresponding infinite bare lattice.
