Analytical solutions of conformable time, space, and time–space fractional KdV equations
(2018)
In this study, we consider the Korteweg–de Vries (KdV) equation for solitary waves in the domain ofconformable fractional calculus. By means of this fractional theory, we obtain exact solutions for time, space, andtime–space ...
Electrical characteristics of Au/n-GaAs structures with thin and thick SiO2 dielectric layer
(Pleiades Publishing Inc, 2011)
The aim of this study, to explain effects of the SiO2 insulator layer thickness on the electrical properties of Au/n-GaAs Shottky barrier diodes (SBDs). Thin (60 ) and thick (250 ) SiO2 insulator layers were deposited on ...
Trace metal and radionuclide pollution in marine sediments of the Aegean Sea (Izmir Bay and Didim)
(Springer, 2013)
To determine radioactivity and trace metal levels, surface sediments were collected from two important areas (A degrees zmir Bay and Didim) in the Aegean Sea region of Turkey, and were analyzed for concentrations of Po-210, ...
Characterization of an AlN buffer layer and a thick-GaN layer grown on sapphire substrate by MOCVD
(Springer, 2011)
An AlN buffer layer and a thick-GaN layer for high-electron-mobility transistors (HEMTs) were grown on sapphire substrate by metal-organic chemical vapor deposition (MOCVD). The structural and morphological properties of ...
Effects of high-temperature AIN buffer on the microstructure of AlGaN/GaN HEMTs
(Pleiades Publishing Inc, 2013)
Effects on AlGaN/GaN high-electron-mobility transistor structure of a high-temperature AlN buffer on sapphire substrate have been studied by high-resolution x-ray diffraction and atomic force microscopy techniques. The ...
Ti doped amorphous carbon (Al/Ti-a:C/p-Si/Al) photodiodes for optoelectronic applications
(Elsevier Science Bv, 2018)
Electrochemical deposition technique was used to fabricate titanium doped amorphous carbon (Ti doped a:C) Al/Ti-a:C/p-Si/Al photodiode. The effects of illumination on the current voltage (I-V) characteristics of the ...
Solutions of local fractional sine-Gordon equations
(Taylor & Francis Ltd, 2019)
In this paper, we study sine-Gordon equation in order to obtain exact solitary wave solutions in the domain of fractional calculus. By using the definition of conformable fractional derivative, we obtain analytical solutions ...
Solution of Schrodinger equation for two different potentials using extended Nikiforov-Uvarov method and polynomial solutions of biconfluent Heun equation
(Amer Inst Physics, 2018)
Exact solutions of the Schrodinger equation for two different potentials are presented by using the extended Nikiforov-Uvarov method. The first one is the inverse square root potential which is a long-range potential and ...
Distribution of natural radionuclide concentrations in sediment samples in Didim and Izmir Bay (Aegean Sea-Turkey)
(Elsevier Sci Ltd, 2012)
Natural and artificial radionuclide pollutants of the marine environment have been recognized as a serious environmental concern. The natural radioactivity activity concentrations of Ra-226, U-238, Th-232 and K-40 were ...
Structural investigation and electronic band transitions of nanostructured TiO2 thin films
(Wiley-V C H Verlag Gmbh, 2011)
Titanium dioxide (TiO2) thin film was deposited on n-Si (100) substrate by reactive DC magnetron sputtering system at 250 degrees C temperature. The deposited film was thermally treated for 3 h in the range of 400-1000 ...
