Structural and elastic properties of binary semiconductors from energy gaps

Abstract

In the present work, we have calculated the structural and mechanical properties of II–VI and III–V tetrahedral semiconductors using some empirical relations. The calculated properties are then correlated with the optical energy gap of respective semiconductors. We carried out a comparative analysis between the predictions obtained from different empirical relations. An exponential relationship is proposed to obtain plasmon energy of binary tetrahedral semiconductors directly from their energy gap. The plasmon energy have been correlated with some of the semiconductor properties. The predicted values of the structural and elastic properties of the semiconductors from a recently proposed Tripathy relation are found to be compatible with those from many other established empirical formulae.
