Characteristic evaluation on spray-deposited WFTO thin films as a function of W doping ratio
(Nonferrous Metals Soc China, 2014)
In this work, F and F + W simultaneously doped SnO2 highly transparent conducting thin films were deposited on glass substrates at (500 +/- A 5) A degrees C temperature by the spray pyrolysis method. Microstructural, ...
Investigation of Cd1-xCoxS diluted magnetic semiconductor thin films fabricated by chemical bath deposition method
(Elsevier Science Sa, 2014)
Chemical bath deposition method was used for preparation of Cd1-xCoxS thin films. the effects of Co doping and thermal annealing on structural, optical, electrical and magnetic properties of CdS thin films were investigated. ...
An investigation of the Nb doping effect on structural, morphological, electrical and optical properties of spray deposited F doped SnO2 films
(Iop Publishing Ltd, 2013)
F and Nb + F co-doped SnO2 thin films were deposited on glass substrates by the spray pyrolysis method. the microstructural, morphological, electrical and optical properties of the 10 wt% F doped SnO2 (FTO) thin films were ...
Influence of Ge content and annealing conditions on the PL properties of nc-Si1-xGex embedded in SiO2 matrix in weak quantum confined regime
(Elsevier Science Bv, 2014)
Fabrication of Si (nc-Si), Ge (nc-Ge), and Si1-xGex (nc-Si1-xGex) nanocrystals embedded in SiO2 matrix is achieved by thermal annealing of magnetron-sputtered thin films. Effects of annealing conditions, namely duration ...
Structural characterizations and optical properties of InSe and InSe: Ag semiconductors grown by Bridgman/Stockbarger technique
(Elsevier, 2014)
Undoped InSe and Ag doped InSe (InSe:Ag) single crystals have been grown by using the Bridgman/Stockbarger method. the freshly cleaved crystals have mirror-like surfaces even without using mechanical treatment. the structure ...
The magnetic and magnetocaloric properties of CoMnGe1-xGax alloys
(Elsevier Science Sa, 2014)
The magnetic and magnetocaloric properties of CoMnGe1 Ga-x(x) (0.02 <= x <= 0.063) alloys have been investigated by using calorimetric, X-ray diffraction and magnetic measurements. Our results show that the structural and ...
