The adsorption of NO on the Si(1 1 1)-7 Γ 7 surface has been investigated by means of hybrid density functional (B3LYP) cluster model calculations. It is shown that both monomeric and dimeric adspecies can be formed upon NO adsorption. The monomeric adspecies adopt bent configurations with the N-end
Ni films ranging in thickness from 0.4 nm to 50 nm were deposited by evaporation onto terraced SiC (0 0 0 1) substrates at room temperature and annealed at 700 Β°C. The resulting changes in surface composition and morphology were characterized using Auger electron spectroscopy and atomic force micros
