Abstract

We have investigated possible water adsorption forms on S-A, D-A and D-B type stepped Si(100) surfaces. Calculations are performed using the empirical tight binding method. Two types of adsorption models of water on stepped Si(100) surfaces have been considered: the dissociative type (H, OH) and the molecular type (H2O). The results of the density of states indicate a dissociative type of water adsorption on S-A, D-A and D-B type stepped Si(100) surfaces.
