Abstract
Adsorption of Sb on a misoriented Si(111) surface is investigated by t hermodesorption Auger spectroscopy. The spectra reveal that, in the su bmonolayer range, new adsorption states appear for the vicinal surface which do not exist for the nominal one. Quenched molecular-dynamics s imulations, in which Si and Sb are modeled by many-body tight-binding potentials, allow us to interpret these new states as due to a molecul ar adsorption at the steps instead of a dissociative one on the terrac es.
