Abstract

An analytic relation between the bulk modulus of a solid and its equilibrium lattice constant is sought by examining how the various components of the total structural energy scale with distance. Simple formulas are obtained for the bulk modulus and its pressure derivative. A comparison is made with an empirical scaling approach for diamond and zinc-blende materials.
