Optoelectronic and thermoelectric properties of KAuX5 (X = S, Se): A first principles study
(Springer US, 2014-02)
The electronic structure as well as optical and thermoelectric properties of the orthorhombic polychalcogenides of gold KAuX5 (X = S, Se) compounds have been investigated using full-potential linearized augmented plane ...
Photovoltaic characteristics of hybrid MEH-PPV-nanoparticles compound
(Elsevier B.V., 2013)
Organic solar cell research has vastly developed in recent years. These organic solar cells however are still limited to low power conversion efficiencies. This has led to the generation of photovoltaic cells based on ...
Copper ion-exchanged channel waveguides optimization for optical trapping
(Elsevier Ltd., 2013-08)
Optical trapping of particles has become a powerful non-mechanical and non-destructive technique for precise particle positioning. The manipulation of particles in the evanescent field of a channel waveguide potentially ...
Simulation of Brillouin and Rayleigh scattering in distributed fibre optic for temperature and strain sensing application
(Elsevier B.V., 2013)
This paper presents simulations of a distributed fibre optic sensor for temperature and strain sensing. The behaviours of Brillouin and Rayleigh scattering in optical fibres are studied through the backscatter signals. The ...
Electronic spectral parameters and IR nonlinear optical features of novel Ag 0.5Pb 1.75GeS 4 crystal
(Elsevier B.V., 2012-09)
In this paper, we report on novel Ag0.5Pb1.75GeS4 single crystals grown by the Bridgman–Stockbarger method. For these crystals we have performed X-ray photoelectron spectroscopy (XPS) studies of the valence-band and ...
Surface modification via wet chemical etching of single-crystalline silicon for photovoltaic application
(Elsevier Ltd., 2013-11)
The potential of solar cells have not been fully tapped due to the lack of energy conversion efficiency. There are three important mechanisms in producing high efficiency cells to harvest solar energy; reduction of light ...
Comparative study on human and bovine AT-SC isolation methods
(Elsevier Ltd., 2013-11)
Mammalian adipose tissue derived stem cells (AT-SC) have a tremendous potential in regenerative medicine for tissue engineering and somatic nuclear transfer (SNT). The isolation methods of human and bovine adipose tissue ...
Fluorescent and nonlinear optical features of CdTe quantum dots
(Springer Science+Business Media, LLC., 2012-02)
The study of photoluminescence and nonlinear optical properties of red (emitted at 650 nm), yellow (emitted at 570 nm) and green (emitted at 530 nm) CdTe quantum dots (QD) spin coated on quartz substrate that had been ...
Effect of increasing tellurium content on the electronic and optical properties of cadmium selenide telluride alloys CdSe1-xTe x: An ab initio study
(Elsevier B.V., 2011-06-16)
An all electron full potential linearized augmented plane wave method, within a framework of GGA (EV-GGA) approach, has been used for an ab initio theoretical study of the effect of increasing tellurium content on the band ...
First-principles calculations of structural, elastic, electronic, and optical properties of perovskite-type KMgH3 crystals: Novel hydrogen storage material
(American Chemical Society, 2011-03-31)
We report a first-principles study of structural and phase stability in three different structures of perovskite-types KMgH3 according to H position. While electronic and optical properties were measured only for stable ...
