Effect of heat treating metallic constituents on the properties of Cu2ZnSnSe4 thin films formed by a two-stage process
(Elsevier Science Sa, 2017)
In this study Cu2ZnSnSe4 (CZTSe) thin films were grown by a two-stage process that involved sputter deposition of a Cu/Sn/Zn/Cu metallic stack, annealing the stack at various temperatures for 30 min, evaporation of a Se ...
Physical properties of CdS:Ga thin films synthesized by spray pyrolysis technique
(Springer, 2017)
This paper reports the investigation of physical properties of CdS:Ga thin films grown for the first time by a simple spray pyrolysis method as a function of Ga-doping level from 0 to 8 at.%. X-ray diffraction (XRD), ...
A comparison of two methods used for determination of tritium concentration in urine samples by liquid scintillation counter
(Springer Singapore Pte Ltd, 2018)
Background Tritium (3H) emits low-energy beta particles with a maximum energy of 18.6 keV. Liquid scintillation counting technique (LSC) is mostly used for the detection and quantification of low-energy emitters like H-3. ...
Dynamic hysteresis loops of the spin-2 bilayer Ising model
(Elsevier Science Bv, 2018)
Based on the mean-field theory and Glauber-type stochastic dynamics, the dynamic hysteresis loops (DHLs) of the spin-2 Ising model are studied on the bilayer square lattice. the DHLs are given for different values of ...
Optical and electrical optimization of dysprosium-doped CdS thin films
(Springer, 2018)
As-grown and Dy-doped CdS thin films containing concentrations of 1, 2, 3, 4 and 5 at.% Dy atom were prepared via chemical spray route on glass substrates. the constructed thin films were searched through analyzing their ...
Influence of pre-annealing Cu-Sn on the structural properties of CZTSe thin films grown by a two-stage process
(Elsevier Sci Ltd, 2018)
In this study CZTSe thin film were synthesized by a two-stage process that included sequential sputter deposition of Cu and Sn layers forming a Cu/Sn structure, pre-annealing the Cu/Sn structure at 200-380 degrees C for ...
An overview of the ecological half-life of the Cs-137 radioisotope and a determination of radioactivity levels in sediment samples after Chernobyl in the Eastern Black Sea, Turkey
(Elsevier Science Bv, 2018)
A study which determined the activity concentration of Cs-137 in sediments contaminated by effluents from the Chernobyl accident which had collected along the coast of the Eastern Black Sea region in Turkey was carried out ...
Simulation and efficiency studies of optical photon transportation and detection with plastic antineutrino detector modules
(Elsevier Science Bv, 2018)
In this work, the simulation of optical photons is carried out in an antineutrino detector module consisting of a plastic scintillator connected to light guides and photomultipliers on both ends, which is considered to be ...
Resonant tunneling properties of inverted Morse double quantum barrier
(Elsevier Science Bv, 2018)
We study resonant tunneling characteristics of inverted Morse double quantum barrier structures. the effect of electric bias and structure parameters is calculated by using non-equilibrium Green's function method. Results ...
The effect of energy resolution of detection instrument on mass attenuation coefficient
(Iop Publishing Ltd, 2018)
The effect of energy resolution of two detection systems, HPGe and NaI(T1), was determined by Monte Carlo (MC) calculation on mass attenuation coefficients of magnesium (Mg) and tungsten (W). in order to reveal the energy ...
