Optical and photoconductivity spectra of novel Ag 2In 2SiS 6 and Ag 2In 2GeS 6 chalcogenide crystals
(Elsevier B.V., 2012-06)
Complex spectral studies of near-band gap and photoconductive spectra for novel Ag 2In 2SiS 6 and Ag 2In 2GeS 6 single crystals are presented. The spectral dependences of photoconductivity clearly show an existence of ...
Further optical properties of CdX (X¼ S, Te) compounds under quantum dot diameter effect: Ab initio method
(Elsevier Ltd., 2012-09)
For energy band calculations, the indirect energy gap (G X) is calculated using density functional theory
(DFT) of the full potential-linearized augmented plane wave (FP-LAPW) method as implemented in
WIEN2K code. The ...

(Elsevier B.V., 2012-09)
An ab initio investigation of the optical constants of 9-Methyl-3-Thiophen- 2-YI-Thieno [3,2e] [1,2,4] Thriazolo [4,3c] Pyrimidine-8-Carboxylic Acid Ethyl Ester crystal is performed within a framework of local density ...
Optical properties of Si quantum dot potential under pressure effect
(Trans Tech Publications, Switzerland., 2012)
Further study of the quantum dot potential under hydrostatic pressure for Si is presented. This potential has been calculated by means of our recent empirical model. The indirect energy gap (Γ-X) is calculated using the ...
Single-crystal oxoborate (Pb 3O) 2(BO 3) 2WO 4: Growth and characterization
(Elsevier Ltd, 2012-09)
An oxoborate, (Pb 3O) 2(BO 3) 2WO 4, has been prepared by solid-state reaction methods below 620°C. Single-crystal XRD analysis shows that it crystallizes in the orthorhombic group Cmcm with a = 18.480(4) , b = 6.3567(13) ...
First-principles calculations to investigate optical properties of B yAl xIn 1-x-yN alloys for optoelectronic devices
(Elsevier Ltd., 2012-03)
First-principles density-functional theory of Full-Potential Linear Augmented Plane Wave (FP-LAPW) within local density approximation (LDA) of the optical properties of B yAl xIn 1- x-yN systems (with x = 0.187 and y = ...
Evidence of Coulomb correction and spin-orbit coupling in rare-earth dioxides CeO2, PrO2 and TbO2: An ab initio study
(Elsevier B.V., 2012-04)
The current study investigates the structural, elastic, electronic and optical properties of CeO 2, PrO 2 and TbO 2 using the full potential (linearized) augmented plane wave plus local orbital method within the WuCohen ...
Structural and optical investigations of cadmium sulfide nanostructures for optoelectronic applications
(Elsevier Ltd., 2012-11)
Cadmium sulfide (CdS) nanostructures were deposited on glass substrates by sol–gel spin coating technique. X-Ray Diffraction
(XRD) results have indicated that the formation of CdS has hexagonal structure. The lattice constants ...
