The influence of TMGa pre-flow time and amount as surfactant on the structural and optical properties of AlN epilayer
(2022)
AIN is used as a template layer for deep UV (DUV) emitter and detector applications, because of
its wide bandgap and high thermal conductivity. In this study, trimethylgallium (TMGa) source is
used as surfactant to improve ...
Growth and characterization of PALE Si-doped AlN on sapphire substrate by MOVPE
(2022)
In this study, we report different SiH4 flow condition effects on crystal, surface, optical, and electrical characteristics of heteroepitaxial Metal-Organic Vapor Phase Epitaxy (MOVPE) grown AlN layers on sapphire substrates. ...
Performance enhancement of AlGaN deep-ultraviolet laser diode using compositional Al-grading of Si-doped layers
(2022)
Achieving high threshold current density and high optical confinement are big challenges in the realization of
high-performance aluminum gallium nitride (AlGaN)-based deep-ultraviolet (DUV) laser diode (LD). In this
work, ...
The effects of activities of daily living education on the independence and life satisfaction of elders
(2022)
Purpose The aim of this study is to examine the effect of education on the independence levels and life satisfaction (LS) of the elderly in their activities of daily living (ADL). Findings The level of independence in ...
Close oxygen coupled low-pressure chemical vapor deposition growth of high quality β-Ga2O3 on sapphire
(2022)
We report on the close oxygen coupled low-pressure chemical vapor deposition (COC-LPCVD) hetero-epitaxial growth of atomically smooth (− 201) oriented β−
Ga2O3 on c-plane sapphire. Utilizing a dedicated line within the ...
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, ...
pH-controlled charge transfer sensitive 2-aminobenzimidazole modified poly(styrene-co-maleic anhydride) copolymer for selective extraction, pre-concentration and determination of trace Hg2+ and CH3Hg+ in vinegar by combination of ultrasound assisted-cloud point extraction with UV-VIS spectrophotometry
(2022)
In this study, a separation/pre-concentration procedure, ultrasound assisted-cloud point extraction with modified
2-aminobenzimidazole (2-ABzI), was developed for the extraction of trace Hg2+ and CH3Hg+ and from
vinegar ...
ALLYL FUNCTIONALIZED BENZIMIDAZOLIUM-DERIVED AG(I)-N-HETEROCYCLIC CARBENE COMPLEXES: ANTI-BIOFILM AND ANTIMICROBIAL PROPERTIES
(2022)
Microorganisms in the biofilm structure cause severe health problems and economic losses. Therefore, it is
very important to design and screen anti-biofilm molecules that can solve the related problems. This paper is
aimed ...
A benzimidazolium salt as effective corrosion inhibitor against the corrosion of mild steel in acidic medium: experimental and theoretical studies
(2022)
A new benzimidazolium salt (1-Allyl-3-(2,3,5,6-tetramethylbenzyl)-
5,6-dimethylbenzimidazoliumchloride) is characterized by using 1H
NMR and 13C(1H) NMR spectroscopies. The corrosion inhibition
performance of benzimidazolium ...
