ESTIMATION OF THE POLARIZATION AND DISPERSION CORRECTIONS TO THE SURFACE ENERGY OF THE FACES OF METAL CRYSTALS
On the basis of the electronic statistical method, expressions for the dispersion and polarization corrections to the surface energy of the crystal faces 1A of metals at the boundary with vacuum are obtained and their value are calculated. Both corrections are highly anisotropic. The dispersion correction increases the surface energies of the faces (from 3 to 23 %), the polarization correction reduces them by less than 1%. Taking into account these interactions improves the agreement between the calculated surface energy and the experimental data of the melts.
