Ab-initio self-energy corrections in systems with metallic screening
Marco Cazzaniga, Nicola Manini, Luca Guido Molinari +1
The calculation of self-energy corrections to the electron bands of a metal requires the evaluation of the intraband contribution to the polarizability in the small-q limit. When n…
Ab-initio calculation of the vibrational modes of SiH4, H2SiO, Si10H16, and Si10H14O
Katalin Gaal-Nagy, Giulia Canevari, Giovanni Onida
We have studied the normal modes of hydrogenated and oxidized silicon nanocrystals, namely SiH4 (silan), H2SiO (silanon), Si10H16 and Si10H14O. The small clusters (SiH4 and H2SiO)…
Ab-initio calculations of the optical properties of the Si(113)3x2ADI surface
Katalin Gaal-Nagy, Giovanni Onida
We investigated the stable silicon (113) surface with a 3x2ADI reconstruction by ab-initio methods. The ground state properties have been obtained using the density-functional theo…
Dielectric function of the Si(113)3x2ADI surface from ab-initio methods
Katalin Gaal-Nagy, Giovanni Onida
We have investigated the imaginary part of the dielectric function Im(epsilon) of the (113) 3x2 ADI reconstructed surface of silicon. The calculations have been performed for a per…
Ab initio study of reflectance anisotropy spectra of a sub-monolayer oxidized Si(100) surface
Andrei Incze, Rodolfo Del Sole, Giovanni Onida
The effects of oxygen adsorption on the reflectance anisotropy spectrum (RAS) of reconstructed Si(100):O surfaces at sub-monolayer coverage (first stages of oxidation) have been st…
