摘要
The oxidation of hydrogenated silicon surfaces has been induced by irradiation of physisorbed water molecules with low energy electrons (E(i) = 0-20 eV), and characterized using XPS. These results demonstrate that the initial step of the chemisorption process in the low incident energy regime is the resonant formation of the dissociative B-2(1) and (2)A(1) transient (H2O)(.-) states.
