The influence of thickness and ammonia flow rate on the properties of AlN layers
(Elsevier Sci Ltd, 2012)
Undoped AlN layers have been grown on c-plane sapphire substrates by metal-organic chemical vapor deposition in order to study the effects of ammonia (NH3) flow rate and layer thickness on the structural quality and surface ...
Spectroscopic and microscopic investigation of MBE-grown CdTe (211) B epitaxial thin films on GaAs (211)B substrates
(Springer Heidelberg, 2018)
CdTe epitaxial thin films, for use as a buffer layer for HgCdTe defectors, were grown on GaAs (211)B using the molecular beam epitaxy method. Wet chemical etching (Everson method) was applied to the epitaxial films using ...
Levels of Po-210 in some commercial fish species consumed in the Aegean Sea coast of Turkey and the related dose assessment to the coastal population
(Elsevier Sci Ltd, 2013)
Concentrations of Po-210 were determined in the edible muscle tissue of five species of marine fish: Sardine (Sardine plichardus) and Anchovy (Engraulis encrasicolus), Red mullet (Mullus barbatus), Horse mackerel (Trachurus ...
Boron doped graphene based linear dynamic range photodiode
(Elsevier Science Bv, 2018)
The boron-doped graphene oxide film was prepared using drop casting/coating technique. The film was coated by hydrothermal method on p-Si substrate and thus Al/p-Si/B-doped GO/Au diode was fabricated. The structural ...
Seasonal variation of the concentrations of Cs-137 in sediment, sea water, and some organisms collected from Izmir Bay and Didim
(Taylor & Francis Ltd, 2014)
Cs-137 in the marine environment mainly originates from fallout of atmospheric nuclear weapon tests, accidental releases from nuclear facilities, and from the Chernobyl accident. After the latter accident, many studies ...
Annual effective dose of naturally occurring radionuclides in soil and sediment
(Taylor & Francis Ltd, 2014)
In this study, the natural radioactivity level of soils and sediments due to the usage of fertilizers, particularly phosphate fertilizers, in agricultural lands of the Buyuk Menderes River Basin, Western Turkey, have been ...
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 ...
Determination of radiation dose from patients undergoing Tc-99m Sestamibi nuclear cardiac imaging
(Springer, 2019)
To date, myocardial perfusion (MP) has been utilized to assess the adequacy of blood flow to the myocardium in order to determine the ischemic heart diseases. With the advent of SPECT/CT, MP became the most common investigation ...
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 ...
Modeling Superionic Behavior of Plutonium Dioxide
(Walter De Gruyter Gmbh, 2016)
The Bredig transition to the superionic phase indicated with the.-peak in C-p was highly expected for plutonium dioxide (PuO2) as other actinide dioxides. However, least-square fit and local smoothing techniques applied ...
