Characterization of the surface states of Co(0001), Co(111), and ultrathin films of Co on Cu(111)

The surface electronic structure of Co(0001), Co(111), and 2Co/Cu(111) is studied using a parametrized tight-binding Hamiltonian with s, p, and d orbitals in the basis. We compare the calculated local density of states in the vacuum region near the surface with the differential conductance dI/dV obt...
