Resistance of a one-atom contact in the scanning tunneling microscope

View publication

Abstract

The resistance as a function of tip-sample separation in the scanning tunneling microscope is calculated for distances in the transition region between tunneling and point contact. A resistance plateau appears near point contact with value A <>e2, where A is of order unity, its exact value depending on the identity of the tip atom. Good agreement is found with the recent experimental data of Gimzewski and Möller. © 1987 The American Physical Society.
