Ab Initio Study Of Double Oxides ZnX ₂ O ₄ (X=Al, Ga, In) Having Spinel Structure

Electronic structure and optical spectra of ZnX 2 O 4 (X=Al, Ga, and In) have been studied by density functional calculations. It is shown that ZnX 2 O 4 posses a large fundamental band gap and a second gap defined as the energy difference between the two lowest conduction band (CB) energies. The se... View More
