Interface states and the barrier height of Schottky diodes
Abstract
The interface states at metal-semiconductor junctions are still a matter of debate. We present a novel approach to this issue that uses state-of-the-art techniques to prepare silicon surfaces with different surface terminations and employs non-interacting Schottky contacts to measure the barrier height. We report a difference of 50 mV in barrier height for Hg Schottky diodes on Si(111) surfaces with different surface terminations. © 1993.
