UTILITY OF THE PLASMON THEORY OF SURFACE AND INTER FACIAL ENERGIES

摘要

Since both plasm on frequencies and cohesive energies depend primarily on the density of valence electrons in solids, they are intimately connected. This includes a connection between plasmon frequencies, bulk moduli, and surface energies. Then, since plasmons are electromagnetic disturbances, they obey some rules that are independent of the details of system. Therefore, they can be used to estimate the energies of simple interfaces in terms of well-known properties. The purpose of this paper is to show how these various quantities are connected so that interface energies can be estimated from known surface energies, and bulk moduli.
