Plasmon energy and lattice energy of binary tetrahedral semiconductors and I–VII ionic compounds

摘要

Two simple empirical relations have been proposed to estimate lattice energy from plasmon energy and bond length of binary tetrahedral semiconductors A N B8−N (N = 2) and I–VII ionic solids. The estimated values are in excellent agreement with the experimental and reported values. Attempt has been made to give a physical basis of the proposed correlation it has been shown that the constants appearing in the proposed relation are characteristics of crystal structures. Effects of atomic size, coordination and ionicity on the lattice energy have also been discussed.
