Research output: Contribution to journalArticlepeer-review


We report the direct measurement of the excitation of electron-hole pairs at a single-crystal InP (100) surface, induced by the scattering of ground-state Xe atoms over an incident energy range 2 eV<Ei<10 eV. Above EîÄ3 eV the yield is fitted well by an exponential dependence on Ei-1. The incident-energy and angle dependence suggest the creation of a local thermal hot spot with fast electronic equilibration.
