Abstract

Values of bonding energies of s p^3 and s p^2 s-hybrid bonding are calculated in the paper. These calculations are performed according to the conception of the influence of anti-bonding quasi-particles on the interatomic bonding force when the bonding particle takes an anti-bonding position. Melting process of covalent crystals is considered and the critical concentration of anti-bonding quasi-particles, at which the melting process begins, is defined. It may be caused not only by temperature, but by action of light, injection of charge carriers and in other ways. Within the Einstein’s model of solid, the heat capacity is calculated for 3D crystal as well as 2D systems.
