Structural properties of Sb- and Te-based binary compounds: Spin-orbit effect
(Versita Warsaw and Springer-Verlag Wien, 2013-01)
The band structure of AlSb, GaSb, ZnTe and CdTe is calculated using the empirical pseudopotential method (EPM) coupled with spin-orbit (SO) splitting. We applied our empirical model of bulk modulus with SO effect. It has ...
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 ...
Optoelectronic properties of GaAs and AlAs under temperature effect
(Elsevier GmbH, 2013-08)
An application study of optoelectronic properties as a function of the temperature for GaAs and AlAs according to our model has been presented using empirical pseudopotential method (EPM). The structural phase transition ...
Optical properties of GaN nanostructures for optoelectronic applications
(Elsevier B.V., 2013)
Electrochemical deposition method is used to prepare GaN nanostructure. The morphological studies using scanning electron microscopy (SEM), photoluminescence (PL) the refractive index and optical dielectric constant are ...
Structural investigation of Si0.5Ge0.5 alloy for optoelectronic applications: Ab initio study
(Elsevier GmbH, 2013-11)
The structural, electronic and optical properties of the binary silicon-germanium alloy have been investigated using the projector augmented-wave (PAW) calculations with a powerful VASP package (Vienna ab initio simulation ...
Structural, analysis and optical studies of cadmium sulfide nanostructured
(Elsevier Ltd., 2013)
Cadmium sulfide (CdS) thin films of nanostructure were prepared and deposited on glass substrates with Cd:S (1.2 to 0.05 mol/L) annealed at 400ºC and different spin coating speed (1000 and 5000 rpm) using sol-gel spin ...
Structural properties of PbI₂ thin film
(Trans Tech Publications, 2014-01)
Lead iodide (PbI₂) thin films were successfully prepared by thermal evaporation method on a glass substrate at room temperature. The structural analysis of these films was done by XRD. The results revealed that the crystallite ...
Effect of roughness of hypo-and hyper-eutectic Al-Si piston alloy on wear characteristics under lubrication
