Modeling of Optical Band-Gap Values of Mixed Oxides Having Spinel Structure AB₂O₄ (A = Mg, Zn and B = Al, Ga) by a Semiempirical Approach.

ABSTRACT: Spinel oxides with the general formula AB₂O₄ comprise a large family of compounds covering a very wide range of band-gap values (1 eV < E_g < 8 eV) as a function of the nature of the metallic cations A and B. Owing to this, the physical properties of these materials have been largely exploited both from a fundamental point of view, for their variable electronic properties, and for their possible use in numerous engineering applications. Herein, the modeling of ZnAl₂O₄, ZnGa₂O₄, MgAl₂O₄, and MgGa₂O₄ cubic spinel oxides has been carried out by using the semiempirical approach based on the difference of electronegativity between oxygen and the average electronegativit
