Effect of the Hamiltonian parameters on Blume-Capel Ising ferromagnet system with single-ion anisotropy
(Academic Press Ltd- Elsevier Science Ltd, 2016)
The dynamic mean-field approach have been utilized to investigate effect of the Hamiltonian parameters on the dynamic magnetic properties of a Blume-Capel Ising ferromagnet system in two dimensions, comprising a ferromagnetic ...
Electron transport in electrically biased inverse parabolic double-barrier structure
(Iop Publishing Ltd, 2016)
A theoretical study of resonant tunneling is carried out for an inverse parabolic double-barrier structure subjected to an external electric field. Tunneling transmission coefficient and density of states are analyzed by ...
Determination of the local structure of CsBi4-xPbxTe6 (x=0, 0.5) by X-ray absorption spectroscopy
(Royal Soc Chemistry, 2016)
We have studied the local structure and valence electronic unoccupied states of thermoelectric CsBi4Te6 and superconducting CsBi3.5Pb0.5Te6 (T-c similar to 3 K) by extended X-ray absorption fine structure (EXAFS) and X-ray ...
Improving the stability of solar cells using metal-organic frameworks
(Royal Soc Chemistry, 2016)
Although Cu2S-containing chalcogenide solar cells are appealing and cost-effective for photovoltaics (PVs), these materials suffer from rapid performance degradation as a result of the diffusion of copper ions into the CdS ...
A study of temperature dependent local atomic displacements in a Ba(Fe1-xCox)(2)As-2 superconductor
(Royal Soc Chemistry, 2016)
We have studied the local structure of a Ba(Fe1-xCox)(2)As-2 superconductor using temperature dependent extended X-ray absorption fine structure (EXAFS) measurements. Polarized EXAFS at the Fe K-edge on an optimally doped ...
Determination of radioactivity levels of soil samples and the excess of lifetime cancer risk in Rize province, Turkey
(Ijrr-Iranian Journal Radiation Res, 2016)
Background: Turkey, especially the northern part of it, was one of the countries which were contaminated by the Chernobyl accident. Rize is a city located in the Northeastern district of Turkey which was heavily influenced ...
Magnetic properties of spin- Blume-Capel chain under a magnetic field
(Elsevier Ltd, 2021)
A magnetic property of the one dimensional spin-7/2 Blume-Capel model under the magnetic field has been investigated by means of transfer matrix method. Thermodynamic response functions are also obtained for varying values ...
