Theoretical study of the structural, electronic structure, fermi surface, electronic charge density and optical properties of the of LnVO4 (Ln= Sm, Eu, Gd and Dy)
(Electrochemical Science Group (ESG), 2013-08)
We present first-principles calculations of the electronic structure, Fermi surface, electronic charge density and optical properties of LnVO4(Ln= Sm, Eu, Gd and Dy) based on density-functional theory using the local density ...
Photothermal poling of glass complexes Ag2S–Ga2S3–P2S5
(Elsevier Ltd., 2013-10)
The studies of the dc-electric field induced second harmonic generation (SHG) for fundamental wavelength of the Ag2S–Ga2S3–P2S5 using nanosecond Er:glass laser at wavelength 1540 nm and elevated temperatures (thermal poling) ...
Shift of band gap from direct to indirect and optical response of lif under pressure
(World Scientific Publishing Co. Pte Ltd, 2013-04)
We hereby are reporting the transition pressure at which lithium fluoride (LiF) compound transforms from direct band gap to indirect band gap insulator on the basis of FP-LAPW calculations. The fundamental band gap of LiF ...
The influence of the lattice relaxation on the optical properties of GaNxAs1-x alloys
(Elsevier Ltd., 2013-04)
We have investigated the optical properties of the ternary alloys GaNxAs1-x (x=0.25, 0.5 and 0.75) without (we call it as case 1) and with (case 2) the lattice relaxation, using the full potential-linearized augmented plane ...
Density of electronic states and dispersion of optical functions of defect chalcopyrite CdGa2X4 (X = S, Se): DFT study
(Elsevier Limited, 2013)
A density functional theory (DFT) based on full potential linear augmented plane wave (FPLAPW) was used for calculating the electronic structure, charge density and optical properties of CdGa2X4 (X = S, Se) compounds. Local ...
DFT calculation of the electronic and optical properties of Ag 2PdO2 from X-ray and neutron crystallographic data
(Elsevier B.V., 2013)
Electronic and optical properties of ternary silver palladium oxide (Ag2PdO2) are investigated using density functional theory. Two different possible approximations for the exchange correlation potentials were employed. ...
Morphology, analysis and properties studies of CdS nanostructures under thiourea concentration effect for photovoltaic applications
(Electrochemical Science Group, 2013-08)
CdS nanostructures are prepared by sol-gel spin coating method using different thiourea concentrations. The thiourea concentration effect for CdS nanostructures deposited on quartz substrate is studied. The CdS nanostructures ...
Optical properties of ultraphosphate glasses containing mixed divalent zinc and magnesium ions
(Elsevier, 2013-01)
Ternary zinc magnesium ultraphosphate glasses corresponding to (ZnO)x(MgO)30−x(P2O5)70 were prepared by melt quenching technique in the range of 5 ⩽ x ⩽ 20 mol%. The optical absorption spectra of the glasses were measured ...
