Abstract
Metastable deexcitation spectroscopy (MDS) was applied to the study of the electronic structure of Sb/GaAs(110) and H:GaAs(110) systems. For both systems valuable insights into the surface electronic structure (effective surface density of states and surface charge density) were obtained. A surface to volume ratio extremely higher than photoemission was obtained for MDS. For both systems new features, never observed by more conventional surface spectroscopies, were detected.
