Adhesion in Atomic Scale Metal Contacts
Abstract
The adhesion interaction of an Ir tip with Ir and Al surfaces has been investigated using the scanning tunneling microscope. Qualitative differences in the adhesion characteristics have been observed. A cluster model based on effective pair-potentials has been set up to understand adhesion in atomic scale contacts. The model calculation provides a semi-quantitative explanation of the experimental data. In particular it is shown that subtle differences of the atomic interaction potentials have a significant effect on the contact mechanics. Adhesion, Metal Contacts.
