Surface trapping of excitons in rare-gas solids
- 1. Department of Nuclear Engineering and Engineering Physics, University of Virginia, Charlottesville, Virginia 22901
Description
Ejected-atom kinetic energy spectra from electronically excited Ar, Kr, and Xe have been interpreted in terms of two mechanisms: the first due to exciton decay in the surface layer and the second due to exciton decay in the subsurface layers. We use the absolute ejection yields for the surface component to determine the efficiency of the surface layer in trapping excitons produced by incident energetic ions and electrons. Estimates of the ratio of surface-to-bulk exciton trapping efficiencies are 4.7, 6.5, and 3.9 for Ar, Kr and Xe, respectively, at 15 K
