First principle study of electronic structure, chemical bonding and optical properties of 5-azido-1H-tetrazole
(Electrochemical Science Group (ESG), 2013)
First principle calculations were performed to investigate the electronic band structure, density of states, charge density and optical properties of 5-azido-1H-tetrazole. The calculated band structure shows that the ...
Density functional theory calculation of the optical properties and topological analysis of the electron density of MBi2B 2O7 (M = Ca,Zn) compounds
(American Institute of Physics, 2013-02)
The topology of the electron density for congruent melting oxyborate Bi2ZnOB2O6 and CaBi2B 2O7 is studied in light of the theory of atoms in molecules. All the electron density critical points in the unit cell are ...
Influence of varying Germanium content on the optical function dispersion of Fe 2MnSi xGe 1-x: An ab initio study
(Elsevier B.V., 2013-01)
The optical dielectric functions of Fe 2MnSi 1-xGe x alloys for selected concentrations (x=0.0, 0.25, 0.5, 0.75 and 1.0) were investigated. The ferromagnetic Fe 2MnSi xGe 1-x is semiconducting with optical band gaps 0.507, ...
Electronic structure, optical and thermoelectric transport properties of layered polyanionic hydrosulfate LiFeSO₄OH: Electrode for Li-ion batteries
