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 ...
Indoor and outdoor radon measurements at lung cancer patients' homes in the dwellings of Rize Province in Turkey
(Springer, 2018)
In this study, indoor and outdoor radon (Rn-222) surveys were carried out in the summer and winter seasons in homes of one hundred lung cancer patients in the year 2013-2014. the aim was to investigate the relationship ...
Determination of radiological hazard parameters in sea snails (Rapana venosa) in the East Black Sea Coast of Turkey
(Pergamon-Elsevier Science Ltd, 2018)
The aim of this study was to determine the activity concentrations and radiological hazard parameters of Cs-137 and K-40 in soft tissue samples of sea snails (Rapana venosa) collected from 12 different stations in the East ...
Sm-doped CdS thin films prepared by spray pyrolysis: a structural, optical, and electrical examination
(Springer, 2018)
Virgin and Sm-doped CdS thin films were prepared by spray pyrolysis route on glass substrates. the influences of Sm-doping amount on structural, topographical, optical and electrical properties were examined. It was found ...
Cu(In,Ga)(Se,Te)(2) films formed on metal foil substrates by a two-stage process employing electrodeposition and evaporation
(Elsevier Science Sa, 2018)
Cu(In,Ga)(Se,Te)(2) or CIGST films were grown over molybdenum coated stainless steel foil substrates using a two-stage technique. the process involved deposition of a Cu-In-Ga/Se-Te precursor stack over the Mo layer using ...
IR laser line scanning treatments to improve levitation forces in MgTi0.06B2 bulk materials
(Elsevier Science Sa, 2019)
Infrared (IR) laser-line scanning has been widely used to induce different surface microstructures in a broad range of materials. in this work, this laser configuration was applied on the surface of MgTi0.06B2 bulk samples ...
Enhanced magnetic levitation and guidance force in MgB2 bulks by synthetic engine oil immersion
(Springer, 2019)
We have used Synthetic engine oil' as a rich easily accessible carbon source and investigated the effect of engine oil on the microstructure, critical current density (J(c)), vertical levitation force (F-z) and guidance ...
A study of the radiological baseline conditions around the planned Sinop (Turkey) nuclear power plant using the mapping method
(Springer, 2019)
This study makes a first attempt at a detailed estimation of the background radioactivity level and its distribution at the Sinop nuclear power plant site. the activity concentration levels of Ra-226, Th-232, K-40 and ...
The local structure and magnetic correlations in La(Fei(1-x)Mn(x))AsO system
(Pergamon-Elsevier Science Ltd, 2019)
The local structure of La(Fei(1-x)Mn(x))AsO, showing suppression of long-range magnetic order by Mn-substitution, has been studied. Extended X-ray absorption fine structure (EXAFS) measurements at As K-edge and Fe K-edge ...
