Correlation of stimulatedH+-desorption threshold with localized state observed in Auger line shape—Si(100): H

Abstract
We report the first observation of a localized two-hole electronic excitation on a covalently bonded surface. We find that the electron-stimulated desorption threshold for this system corresponds to the localized state energy. This suggests that localized multihole excitations are important dissociation channels in extended covalent systems.
