The relations among the quantities participating in surface formation have been studied on the basis of the following assumptions: (i) There is an analogy between surface formation and vaporization. (ii) The surface tension as a function of temperature is given by the equation, γ∝(1−T⁄Tc)B, where Tc is the critical temperature and B is the exponent.
Based on the above assumptions the following expressions for the relations among surface quantities are determined by statistical analysis of experimental data: (1) The surface entropy is given by the equation, s≈0.1S, where S the specific vaporization entropy in J/(m2·K), defined as the vaporization entropy per unit area of the monatomic layer in bulk. (2) The surface tension is given by the equation, γ=1.536×104 S1.62, where γ is the surface tension in N/m. (3) The surface tension is given by the equation, γ=0.152+4.61×10−4 Ev⁄V2⁄3, where Ev, is the formation energy of a vacancy in eV and V is the atomic volume in m3.
