Abstract

We report the emission of ions from single crystal surfaces due to the scattering of hyperthermal Xe over the energy range 6 < E_i < 20 eV. We observe Ga⁺ from GaAs(110), In⁺ from InP(100), and alkali and other impurity ions from all surfaces. At E_i = 16 eV the ion emission probability for In⁺ reaches 1 × 10^-3. The yields increase as the Xe incident angle goes towards grazing, have a similar Xe kinetic energy dependence, and a common threshold near 6.5 eV at the incident angles of maximum efficiency. We discuss possible mechanisms for ion emission due to hyperthermal Xe scattering.
