Surface trapping during hyperthermal energy scattering

We present the results of a detailed investigation of surface trapping duri ng the scattering of hyperthermal (less than or equal to 600 eV) energy ion s from metallic surfaces. Recent experiments have revealed that trends in s urface trapping probabilities are highly dependent on factors such as incid ent ion energy, species, and angle. By comparing the results of classical t rajectory simulations to experimental data, we show that the surface corrug ation seen by the incident ions plays a key role in determining surface tra pping trends for ions incident at hyperthermal energies.
