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 ...
Investigated stiffness of high performance superconductivity with nanoceria incorporated into polycrystalline magnesium diboride
(The Institution of Engineering and Technology, 2012-08)
Polycrystalline MgB 2 was prepared with different amounts of nano-sized CeO 2 inclusions, subjected to X-ray diffraction, scanning electron microscopy and atomic force microscopy characterisation. The nano-CeO 2 inclusions ...
Bismuth in gallium arsenide: Structural and electronic properties of GaAs 1-xBi x alloys
(Elsevier Inc., 2012-02)
The structural and electronic properties of cubic GaAs 1-xBi x alloys with bismuth concentration 0.0, 0.25, 0.50, 0.75 and 1.0 are studied using the 'special quasi-random structures' (SQS) approach of Zunger along with the ...
Electronic structure and magneto-optic Kerr effect in ferromagnetic titanium oxyphosphates Li 0.50Co 0.25TiO(PO4): An ab-initio study
(Elsevier Ltd., 2012-06)
The X-ray diffraction for Li 0.50Co 0.25TiO(PO 4), was used as a starting point to perform structural optimization by minimizing the forces acting on the atoms. We have performed a comprehensive theoretical study of ...
DFT calculation for elastic constants of orthorhombic structure within WIEN2K code: A new package (ortho-elastic)
(Elsevier B.V., 2012-12)
A new package for calculating the elastic constants of orthorhombic structure is released. The package called ortho-elastic. The formalism of calculating the ortho-elastic constants is described in details. The package is ...
Amino acid 2-aminopropanoic CH 3CH(NH 2)COOH crystals: Materials for photo- and acoustoinduced optoelectronic applications
(Springer Science+Business Media, LLC, 2012-10)
Photo-induced treatment of L-alanine single crystals grown by slow evaporation method at an ambient temperature was performed using a 25 ps Nd:YAG pulsed laser in the presence of an external acoustic filed. The changes of ...
