Abstrakt: Focuses on the tunneling spectroscopy of sulfur- and oxygen-terminated n- and p-type gallium arsenide (GaAs) (110) surfaces for air and ultrahigh-vacuum conditions. Comparison between tip-induced and surface-state-induced band-bending effects in the tunneling spectra of passivated semiconductor surfaces; Advantages of molecular-beam-epitaxial-grown test structures over silicon; Role of surface states; Experimental procedures for GaAs passivation.
