Systematic optical study of high-x InxGa1-xAs/InP structures for infrared photodetector applications
(10.12.2022)
Optical and structural properties in high-x InxGa1-xAs (x > 0.65) samples with varying indium concentration
grown on InP (100) substrate are reported. By increasing the indium fraction, it was found by the high-resolution
X-ray ...
In-situ thermal cleaning of the sapphire substrate and temperature effect on epitaxial AlN
(3.09.2022)
The impact of thermal surface cleaning on epitaxial AlN thin films grown on sapphire is investigated in this study
at various temperatures. The sapphire substrate is cleaned in a hydrogen environment. Structural, optical, ...
Optical and nano-mechanical characterization of c-axis oriented AlN film
(19.05.2022)
This paper reports the temperature effects on the optical properties of metalorganic vapour-phase epitaxy
(MOCVD) grown c-axis oriented AlN epilayer thin film studied by in-situ high-temperature spectroscopic
ellipsometry. ...
Determination of Optical Properties of MOVPE‑Grown InxGa1‑xAs/ InP Epitaxial Structures by Spectroscopic Ellipsometry
(24.08.2022)
InxGa1−xAs epitaxial layers with different AsH3 flows have been grown on InP substrate with the MOVPE system. It has been found that AsH3 flow variation affects the In concentration of InGaAs/InP structure because the ...
Prediction of average shape values of quartz particles by vibrating disc and ball milling using dynamic image analysis based on established time-dependent shape models
(2022)
Although grinding kinetics has been the subject of many researches, there is no research examining the shape kinetics of particles ground by different mills using dynamic image analysis (DIA) in the literature. In this ...

Türkiye’de 2015 ile 2022 yılları arasında meydana gelen orman yangınlarının coğrafi bilgi sistemleri ile zamansal ve mekânsal analizi
(01.11.2023)
Dünyada orman yangınlarının can ve mal kaybına neden olan sosyal, ekonomik ve ekolojik olmak üzere maddi ve manevi birçok sonuçları vardır. Son yıllarda dünya genelinde orman yangınlarında hem sıklık hem de büyüklük açısından ...
InncreaWatch
(27.05.2023)
Laboratuvar analizlerinde kullanılan en önemli reaktiflerden bir tanesi saflaştırılmış (utra-saf) su'dur. Bu cihazlarının birincil sarf maddesi olan ultra saf suyun kalitesi, gerçekleştirilen laboratuvar analizin doğruluğuna ...
Investigation of structural, morphology, and conduction mechanism of GO–Fe3O4–TiO2 composite material
(2023)
The graphene oxide composite (GO), iron oxide (Fe3O4), and titanium dioxide
(TiO2) were prepared by the sol–gel process. The surface of GO is coated with
TiO2 and Fe3O4 nanoparticles, and the composite contains 10.26% ...
Comparison of Particle Shape, Surface Area, and Color Properties of the Calcite Particles Ground by Stirred and Ball Mill
(2023)
Since the particle size, shape, specific surface area, and purity of the ground calcium carbonate (GCC) decide its usability in the paper, paint, and plastic industries, the effect of grinding is important. However, the ...
