An investigation on CdSeTe/CdTe stacks deposited by evaporation: Impact of Halide treatment depending on the applied surface
(Wiley, 2024)
Among the methods applied to modify the characteristics of CdSeTe/CdTe stacks, one of the most well-known and widely used procedures is the CdCl2 halide treatment. In this connection, the influence of CdCl2 on microstructural ...
Binding energies of shallow donors in polar ZnO/ZnBeO quantum well
(Elsevier, 2024)
This study examines a single wurtzite ZnO/ZnBeO quantum well structure oriented in the polar c -direction. The focus is on investigating the binding energies associated with an impurity donor atom within this system. To ...
Preparation and characterization of new window material CdS thin films at low substrate temperature (<300 K) with vacuum deposition
(Elsevier, 2011)
Low-temperature vacuum deposition instead of the commonly used vacuum deposition at high substrate temperatures has been applied to prepare new window material CdS thin films. The structural, optical and electrical properties ...
Effect of CdCl2/annealing on the crystalline transformation of CdTe thin films grown by evaporation at a low substrate temperature
(TÜBİTAK, 2011)
The structural and optical properties of CdTe thin films prepared at a low substrate temperature were investigated before and after the CdCl 2/annealing. The crystal structure of CdTe film was cubic with a strong (111) ...
Radionuclide concentration in tea, cabbage, orange, kiwi and soil and lifetime cancer risk due to gamma radioactivity in Rize, Turkey
(Wiley, 2011)
BACKGROUND: In this study, the activity concentrations of 232Th, 238U, 40K and 137Cs were measured in tea, cabbage, orange, kiwi and soil samples collected from different stations using gamma spectrometry with a high-purity ...
Fuzzy logic controlled buck-boost DC-DC converter for solar energy-battery system
(IEEE, 2011)
In this paper, a Fuzzy Logic Controlled (FLC) buck-boost DC-DC converter for solar energy-battery systems is presented. General design of a fuzzy logic controller (FLC), based on Matlab/Simulink is performed. This design ...
Study of microwave surface resistance of type-II superconductors carrying transport current
(Wiley, 2011)
We investigate the microwave surface resistance of an infinitely long type-II superconductor in the critical state carrying transport DC current, in the absence and in the presence of external magnetic fields. Calculations ...
Structural and optical properties of ZnO thin films by the spin coating Sol-Gel method
(Kluwer Academic Publishers, 2011)
ZnO thin films were deposited onto glass subsrates by a Sol-gel spin coating method. The structural and optical properties of ZnO thin films were investigated. The molar ratios of the zinc acetate dihydrate to Monoethanolamine ...
Heavy metal analysis around Murgul (Artvin) copper mining area of Turkey using moss and soil
(Elsevier, 2012)
This research investigates heavy metal pollution around one of the most important mining areas in Turkey, the Murgul mining, by means of analyzing moss and soil samples collected in the neighborhood of the copper mining ...
Radioactivity and heavy metal concentrations in food samples from Rize, Turkey
(Wiley, 2012)
BACKGROUND: Rize in Turkey was contaminated by the Chernobyl accident in 1986. A comprehensive study was planned and carried out to determine the radioactivity levels and heavy metal concentrations in four food categories ...
