| Summary, etc | This thesis consist of the analysis of electronic structures to diagnose the optical properties and thermoelectric characteristics of spinel compounds XZn2O4 (X = Ge, Sn)<br/>having cubic structure. Properties are examined and required parameters are calculated with the help of DFT based FP-LAPW approach. The precise density of states (DOS) and<br/>band structures (BS) diagrams, figured by using mBJ functional show the semiconducting natures of XZn2O4 (X = Ge, Sn) respectively. Also the direct band gaps of the studied compound reveals them optically active for the photonic applications and<br/>optoelectronic devices. The total energies vs volume shows the structural stability for the studied compounds. Due to presence of strong hybridization among O atom with p-states, Zn with d-states, the Zn atom show decay in the magnetic moments also it occurs at the X site and O site. The plotted absorption coefficient approved for blue shift, hence the studied spinel oxides are recommended in optical applications. Also these spinel oxides are very suitable for thermoelectric devices and applications.<br/> |
