摘要：

From a comparison between calculated STM images of Xe on Cu(110) and experimental images of Xe on Ni(110), tip apex structures are proposed for the Eigler atomic switch in the <<on>> and <<off>> states. After the voltage pulse and before a scan, the Xe is found to be on the top site of the apex. A scan induces a migration of the Xe on the apex facet opposite to the Cu(110) step edge. The calculated <<on/off>> current intensity ratio of the switch is in good agreement with the experimental one.
