摘要: Abstract The electronic states of the pyramidal cluster model Si(111)7 × 7 surface are fully elucidated by first-principles LCAO-X α -force calculations. obtained level structure various dangling bonds is consistent with observed UPS and ELS spectra. mechanism to stabilize discussed on basis force acting each atom in cluster.
