Modeling of Temperature Contribution to the Interphase Energy of the Faces of Cadmium Crystals at the Boundary with Organic Liquids

Abstract

Of great interest is the study of the influence of various factors on the surface characteristics of metallic crystals in contact with organic matter. The features of this interface allow you to create materials with practically useful properties used in various devices. A significant contribution to the surface characteristics of metals is made by free electrons, which at room temperature have sufficient energy of thermal motion to leave the atom and move freely in the crystal lattice. Such electrons do not experience collisions with ion cores and do not deviate from rectilinear motion at distances much larger than the constant lattice, since the ions are located in a regular periodic lattice in which electron waves propagate freely. They also rarely scatter on other conduction electrons due to the Pauli principle. A set of non-interacting free electrons in metals form an electronic liquid. In this paper, a modified version of the electron – statistical method for calculating the temperature contribution to the interfacial energy of metals at the boundary with nonpolar organic liquids is developed. The dependence of the temperature contribution to the interphase energy on the dielectric constant of the liquid and the orientation of the metal crystal are obtained.
