Abstract: HC.00001 : Probing Chemicurrent Production in Ultrathin Film Schottky Diode Devices using Hyperthermal Energy Ion Beams.
10:15 AM–10:27 AM
We are investigating the interactions of hyperthermal energy ions with ultrathin film Schottky diode devices, probing the role of ion-surface impact events and charge transfer on chemicurrent production. Chemicurrents are a fundamental ``chemical current'' that arises from electron-hole pair production at a diode surface. To date, these currents have been explored only for thermal energy gas-surface impacts. Using a UHV beamline to produce well-collimated monoenergetic noble gas and alkali-metal beams from 10 eV to 10 keV, we have the unique flexibility to probe our in-house designed diode devices with a wide range of incident species, energies, and charge states. Preliminary results are presented and discussed in the context of basic gas-surface energy transfer processes.
