Abstract
Tunneling spectroscopy of sulfur- and oxygen-terminated n- and p-type GaAs (110) surfaces is reported for air and ultrahigh-vacuum conditions. Simulations of the complete I-V characteristics with explicit inclusion of surface states within the planar junction theory are described and compared to experiment. These results provide a comprehensive understanding of the interplay between tip-induced and surface-state-induced band-bending effects observed in the tunneling spectra of passivated semiconductor surfaces.Citation
