In-situ and ex-situ face-to-face annealing of epitaxial AlN
(2022)
AlN films have been deposited on c-plane sapphire substrates by metalorganic-vapor-phase-epitaxy (MOVPE).
The changes in the film structure have been investigated by applying different annealing processes which are exsitu ...
In-situ thermal cleaning of the sapphire substrate and temperature effect on epitaxial AlN.
(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, ...
A kinetic study on the nitrification process in the upflow submerged biofilter reactor
(Environmental Technology, Taylor and Francis, 2022)
In extent of this study, ammonium removal from wastewater through biological nitrification
process was performed in upflow biofilm reactors. The effects of hydraulic retention time (HRT)
and nitrogen loading rate (NLR) ...
Experimental study of seismic torsional behavior of reinforced concrete walls
(2022)
In this paper, the seismic torsional behavior of reinforced concrete walls has been studied
experimentally. Reinforced concrete walls having 7, 6, and 5 aspect ratios have been produced
on a 1/2 scale. Three specimens ...
Neural network estimations of annealed and non-annealed Schottky diode characteristics at wide temperatures range
(15/06/2022)
n this study, Artificial Neural Network (ANN) model has been proposed to characterize the annealed and the
non-annealed Schottky diode from experimental data. The experimental current values of Ni/n-type 6H–SiC
Schottky ...

Characterization of the co-seismic pattern and slip distribution of the February 06, 2023, Kahramanmaras, (Turkey) earthquakes (Mw 7.7 and Mw 7.6) with a dense GNSS network
(09.11.2023)
Two consecutive earthquakes with the magnitudes of Mw 7.7 and 7.6 (February 06, 2023) occurred on the East Anatolian Fault Zone (EAFZ) segments and unfortunately resulted in significant devastation to human life and cities ...
A Comparative Evaluation of Earthquake Code Change on Seismic Parameter and Structural Analysis; A case of Turkey
(2022)
Turkey, which is one of the countries with high seismic risk, has made significant changes in both seismic risk maps and
seismic design codes over time by adapting to these developments. Information about the important ...
Theoretical analyses of the carrier localization effect on the photoluminescence of In-rich InGaAs layer grown on InP
(2022)
The free buffer InGaAs/InP structure has been elaborated by Metal Organic Vapor Phase Epitaxy (MOVPE). High
indium content is chosen to reduce the bandgap energy of the ternary material with direct bandgap to be promoted ...
Determination of historical graves by ground penetrating radar method: Sakarya Field Battle (August 23 – September 13, 1921, Turkey)
(2022)
The Sakarya Field Battle was the last phase of the forward operation of
the Greek Asia Minor Army, which started at the end of March 1921.
Although there are contradictory numbers regarding the losses of the
parties in ...
