Characterization of a multilayer GaAs/AlGaAs broadband quantum well infrared photodetectors
(2010)
In this study, we report on the investigation of two multilayer GaAs/AlGaAs quantum well infrared photodetectors designed for 8-12 µm spectral range detection. Fabricated devices were characterized by current-voltage and ...
Power-loss mechanisms in surface passivated AlGaN/AlN/GaN heterojunctions
(Institute of Electrical and Electronics Engineers Inc., 2016)
The surface passivation effect on the power-loss mechanisms in AlGaN/AlN/GaN heterostructures was investigated. The electron temperatures of hot electrons was obtained from the temperature and the applied electric field ...
Photochemistry of six- and five-membered-ring alpha,beta-unsaturated lactones in cryogenic matrices
(Wiley, 2008)
The photochemistry of representative six and five-membered alpha,beta-unsaturated lactones [alpha-pyrone and some of its derivatives, including coumarin and 3-acetamidocoumarin, 2(SH)-furanone] isolated in cryogenic inert ...
Influence of dopant concentration on the optical properties of ZnO: In films by sol-gel method
(Elsevier Science Sa, 2009)
Undoped and in doped ZnO films have been deposited by sol-gel spin coating method. The effect of indium, incorporation on structural and optical properties of ZnO films has been investigated. X-ray diffraction patterns of ...
Gibbs Free Energy Assisted Passivation Layers
(Spie-Int Soc Optical Engineering, 2016)
Reduction of surface leakage is a major challenge in most photodetectors that requires the elimination of surface oxides on etched mesas during passivation. Engineering the passivation requires close attention to chemical ...
Dielectric Properties of Isotactic Polypropylene and Montmorillonite Nanocomposites
(IEEE, 2010)
Polymer nanocomposites typically consist of inorganic particles dispersed in a polymer matrix. Layered-silicate-based polymer nanocomposites have great potential as low-cost, highperformance materials with various engineering ...
Electrodeposited SnS film for photovoltaic applications
(Pergamon-Elsevier Science LTD, 2014)
SnS film has been produced by electrodeposition technique onto ITO (indium-tin-oxide) coated glass substrates using aqueous solution containing SnCl2 and Na2S2O3. The pH of the solution was adjusted to 1.8 by drop-wise ...
Some structural properties of CdO : F films produced by ultrasonic spray pyrolysis method
(Elsevier Science Sa, 2007)
The fluorine doped cadmium oxide (CdO:F) samples have been deposited at 250 degrees C by ultrasonic spray pyrolysis method. Cadmiumacetatdihydrat and ammonium fluoride have been taken as a source of cadmium and fluorine-dopant ...
Adsorption and solid phase extraction of 8-hydroxyquinoline from aqueous solutions by using natural bentonite
(Elsevier Science BV, 2010)
The nitrogen-heterocyclic compound 8-hydroxyquinoline (8HQ) is one of the components of coal tar and has a wide variety of uses in industry. Because of its toxicity for aquatic organisms and harmful effects for human health, ...
Nanolabel for TNF-alpha determination
(Elsevier Science BV, 2013)
Tumor necrosis factor-alpha (TNF-alpha), also known as cachectin, is one of the most important regulatory cytokines and mediates a variety of cell functions, including the stimulation of nitric oxide (NO) production which ...
