Electronic Impurity Levels in SmS Compounds

We study the electronic energy levels on the nearest neighbours to a substitutional anionic atom in SmS compounds. In agreement with an experimentally observed collapse of doped crystals, the impurity is essentially supposed to introduce a drastic change in the dd hopping integrals between near neighbour conduction band orbitals of samarium. We find that a bound state extracted from the conduction band and falling below the f levels is able to drive an f quasistate above the Fermi level through fd hybridization.
