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 ...
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 ...
Comprehensive growth and characterization study of GeOx/Si
(15.02.2023)
In this study, the reactive radio frequency magnetron sputtering (RFMS) method under varying thickness
was used to deposit GeO x on Si substrate at room temperature. The effect of thickness on the structural
and optical ...
Investigating the optical, electronic, magnetic properties and DFT of NiO films prepared using RF sputtering with various argon pressures
(28.04.2023)
In this study, we investigated the structural, optical, magnetic, and conductive properties of nickel oxide (NiO)
films on glass substrates deposited using Radio Frequency (RF) magnetron sputtering with varying Ar ...
Experimental insights toward carrier localization in in-rich InGaAs/InP as candidate for SWIR detection: Microstructural analysis combined with optical investigation
(15.01.2023)
Hyperspectral imaging has been flourished thanks to the huge investigation of the infrared spectrum from NIR to
LWIR bands. The ternary InGaAs has been investigated herein in the context of studying the structural ...
Modeling of temperature‑dependent photoluminescence of GaN epilayer by artificial neural network
(22.06.2023)
Artificial neural networks (ANNs) are a type of machine learning model that are designed to mimic the structure and function
of biological neurons. They are particularly well-suited for tasks such as image and speech ...
Effect of substrate temperature on Raman study and optical properties of GeOx/ Si thin films
(14.10.2023)
In this study, GeOx
thin films were deposited onto Si substrates using the RF magnetron sputtering method. We looked at
how the temperature of the substrate affected the Raman spectra and optical characteristics of ...
