Abstract

We present a nonlocal theory of the dispersion force of physisorption for non-polar atoms or molecules. The calculation uses linear response theory and the surface impedance method. The results generalize those presented previously, which relied on a local theory of the dielectric response. Also included in the treatment is the role of diffuseness of the interface between substrate and vacuum. Adatom dipole and quadrupole fluctuations are treated. Several diverse contributions to the potential are thus calculated, giving rise to a substantial modification of the conventional expression V {reversed tilde equals} -C₃(z-z₀)^-3, especially at small separation z.
