Abstract
We investigated the clean surface fo a Pt(100) single crystal in its stable (5 × 20) and metastable (1 × 1) configurations by ultraviolet photoelectron spectroscopy, Auger electron spectroscopy, and low-energy electron diffraction. The photoelectron spectrum of the (1 × 1) surface for eV is characterized by a narrow peak 0.25 eV below the Fermi level; it is suggested that this peak is due to a maximum in the surface density of states associated with an electronic surface resonance or surface state on the (1 × 1) surface.
