We present a theoretical investigation of the electronic structure of the ideal (001) surface of Ir and Pt. Surface band structures and local densities of states have been determined using a parametrized linear combinatiion of atomic orbitals for a film of fourteen (001) atomic planes. Various surfaces states and resonances arise in correspondence of the gaps of the projected bulk band structure. Our results explain the experimetnal data, obtained in field ion emission and conventional photoemission experiments, showing a surface sensitive structure in the proximity of the Fermi energy.

Abstract
We present a theoretical investigation of the electronic structure of the ideal (001) surface of Ir and Pt. Surface band structures and local densities of states have been determined using a parametrized linear combinatiion of atomic orbitals for a film of fourteen (001) atomic planes. Various surfaces states and resonances arise in correspondence of the gaps of the projected bulk band structure. Our results explain the experimetnal data, obtained in field ion emission and conventional photoemission experiments, showing a surface sensitive structure in the proximity of the Fermi energy.
