Description
Summary:Within the framework of the local nonhomogeneous electroconductive solid model the regularities of near surface non-homogeneity in half-space and layer are studied. Two characteristic sizes are inherent to this non-homogeneity. It is shown that in a free of force load body the values of surface stress and surface, charge are uniquely defined by physical parameters of the material and the body. The electric double layer is the result of taking into account the structural non-homogeneity of material and the forces of Coulomb interaction. References Nepijko, S. A. (1985).
