Surface corrugation effects on the adsorption dynamics of xenon on Pt(110)−(1 × 2)

Abstract The adsorption probability of xenon on Pt(110)(1 × 2) shows a strong dependence on both the polar (θ i ) and aximuthal angles of incidence. For atoms incident along the (110) direction the adsorption probability increases slowly with increasing angle of incidence, scaling as E i , cos 0.5 θ, whereas along the (100) azimuth it decreases with increasing angle of incidence, exhibiting “negative” energy scaling. The hard cube washboard model does not account quantitatively for these differences with a single consistent set of parameters.
