We have investigated the electronic band structure of hydrogen and oxygen adsorbed single and double layer stepped Si(100) surfaces by Empirical Tight Binding (ETB) method. The total electronic energies of the H,O-S-A, D-A, D-B type stepped Si(100) systems are calculated with limited number of hydrogen and oxygen atoms separately to find out the most probable adsorption sites of the adatoms in the initial stage of hydrogenation and oxidation.

Adsorption of oxygen and hydrogen on stepped Si(100) surface Salman, SA; Katırcıoğlu, Şenay (1999-06-01) We have investigated the electronic band structure of oxygen and hydrogen adsorbed stepped Si(100) surface using the empirical tight binding method (ETB). The total electronic energies of the O-stepped and H-stepped Si(100) systems are calculated with a limited number of oxygen and hydrogen atoms separately to find out the most probable adsorption sites of the adatoms in the initial stage of oxidation and hydrogenation.
Electronic band structure of stepped Si(100) surfaces Salman, SA; Katırcıoğlu, Şenay; Erkoc, S (2001-02-01) We have investigated the electronic band structure of five different stepped Si(100) surfaces by the empirical tight binding (ETB) method. It has been found that the interaction states have approximately the same energy values for the stepped surfaces with a similar dimer bond nature on the terraces. The single layer stepped models show different density-of-states features than the double layer stepped models.
SIMULATION CALCULATIONS FOR GOLD CLUSTERS ON THE GAAS(110) SURFACE Erkoç, Şakir; HALICIOGLU, T; TILLER, WA (1992-08-15) Energy- and structure-related properties of small gold clusters deposited on the GaAs(110) surface were investigated in this work using a molecular dynamics procedure. A recently developed potential energy function based on two- and three-body interactions was employed in calculating energies and forces. These calculations produced some consistent results with experiments. The three-body interactions involving As atoms in particular, were found to play an important role in determining favorable binding site...
Metallization of the C-60/Rh(100) interface revealed by valence photoelectron spectroscopy and density functional theory calculations Wade, Abdou-Ciss; Lizzit, Silvano; Petaccia, Luca; Goldoni, Andrea; Diop, Djibril; Toffoli, Hande; Fabris, Stefano; Baroni, Stefano (AIP Publishing, 2010-06-01) The electronic structure of single and multiple layers of C-60 molecules deposited on a Rh(100) surface is investigated by means of valence photoemission spectroscopy and density functional theory calculations. The binding of the fullerene monolayer to the metal surface yields the appearance of a new state in the valence band spectrum crossing the Fermi level. Insight into the metallization of the metal/fullerene interface is provided by the calculated electronic structure that allows us to correlate the me...
Bosonic helium clusters doped by alkali metal cations: interaction forces and analysis of their most stable structures Marinetti, F.; Coccia, E.; Bodo, E.; Gianturco, F. A.; Yurtsever, E.; Yurtsever, M.; Yıldırım, Erol (Springer Science and Business Media LLC, 2007-07-01) Ab initio potentials are computed for alkali metal cationic partners interacting with He-4 and an overall many-body potential is constructed for each of the ionic dopants in helium clusters. The structures are then obtained via a genetic algorithm approach and results compared with Basin-Hopping Monte Carlo simulations. The classical arrangements are analyzed and quantum effects discussed in comparison with what has been found with Diffusion Monte Carlo calculations. Further corrections to the classical pic...
