Abstract

The bias voltage dependence of the apparent local barrier height (LBH) corresponding to “work function” at nanometer-scale has been measured by scanning tunnel microscope (STM) on the reconstructed Au (111) surface with Pt-Ir and Au tips at a low bias voltage from ± 50 to ±400 mV. The LBH value measured under a constant-current condition increases with increasing absolute bias voltage. Under a constant current condition, increase of the absolute bias voltage causes increase of the tip-sample separation. Therefore, the result is due to the separation effects rather than bias voltage effects.
