Abstract
The van der Waals contribution to the work of adhesion at metal-oxide interfaces is analytically derived within the framework of a dielectri c continuum model. Calculated estimates are shown to nicely reproduce the trends deduced from measurements of the overall adhesion energy. F urthermore, the quantitative agreement is satisfactory, especially for low-density metals (noble metals). This suggests that the van der Waa ls forces play an important role in the adhesion mechanism at metal-ox ide interfaces.
