Abstract
In angle-resolved secondary-electron—emission spectra from a silicon (111)7×7 surface there are two series of peaks which are not in the spectra of the unreconstructed (111)1×1 surface. These peaks are interpreted by a two-step model; electrons are excited into surface-state resonances lying above the vacuum level, from which states they emerge into the vacuum. The dispersion curves of these states are presented and discussed.Keywords
