Light emission from noble metal surfaces excited by a scanning tunneling microscope has been interpreted as arising from in elastic tunneling excitation of tip-induced plasmon modes. We have extended this work to study the adsorption of oxygen on Ti and have observed the formation of structures with subnanometer lateral dimensions which give rise to clear contrasts in STM topographs and photon intensity maps. The experimental results strongly indicate that these contrasts are due to oxygen-induced variations of the local density of states.

Self Consistency

An ab initio method is developed to calculate the surface electronic structure. The method is based on the tight-binding linear muffin-tin orbitals and real-space recursive Green's function and can achieve self-consistency efficiently. Sample calculations include Fe(001)and Cr(001) systems and are compared with recent experiments using scanning tunneling microscope and photoemission. From the calculated local density of states several prominent surface states above and below the Fermi level are identified and found to agree well with the experimental results.
