STM Imaging of Single-Atom Adsorbates on Metals

Part of the Springer Series in Surface Sciences book series (SSSUR, volume 29)

Abstract

Consider the imaging of a single atom adsorbed on a metal surface in the STM. Ideally, the STM tip will also be one atom adsorbed on a group of other metal atoms. For theoretical purposes, we will model this system using two flat metallic electrodes, each of which has a single atom adsorbed on its surface, with one representing the tip and the other the sample. If we calculate the current that flows between these electrodes when a bias voltage is applied between them, then we can study theoretically many of the basic physical aspects of STM imaging.

The calculations shown in this article are all for a positive background density such that r s = 2 bohr, where (4/3)πrs3n̄ ̄ 1. This corresponds to a typical high-electron-density metal.Google Scholar
