Electrical characterization of sol-gel derived PZT films produced by micropatterning

Near infrared interference filter design and the production with ion-assisted deposition techniques Aydoğdu, Selçuk; Esendemir, Akif; Department of Physics (2012) Near infrared region (NIR) of the electromagnetic spectrum (EM) is defined as 700nm to 1400nm wavelength interval by International Commission on Illumination(CIE). This wavelength interval is extensively used for target acquisition, night vision, wireless communication etc. Therefore, filtering the desired portion of EM spectra becomes a need for that kind of applications. Interference filters are multilayer optical devices which can be designed and produced for the desired wavelength intervals. The product...

Electromagnetic shielding effectiveness of galvanostatically synthesized conducting polypyrrole films in the 300-2000 MHz frequency range Kaynak, A (1996-07-01) Both far-field (plane wave) and near field shielding effectiveness (SE) measurements have been conducted on electrochemically synthesized conducting polypyrrole(PPy) films with wide ranging conductivity levels (10(-2) S/cm to 45 S/cm). Go-axial transmission line, TEM test cell and TE(10) waveguide techniques were employed to measure shielding effectiveness as a function of polymer conductivity, frequency and temperature. Highly doped polypyrrole films exhibited shielding levels, above 40 dB from 300 MHz to ...
Electrical Characterization of ZnInSe2/Cu0.5Ag0.5InSe2 Thin-Film Heterojunction Gullu, H. H.; Parlak, Mehmet (Springer Science and Business Media LLC, 2019-05-01) ZnInSe2/Cu0.5Ag0.5InSe2 diode structures have been fabricated by thermal evaporation of stacked layers on indium tin oxide-coated glass substrates. Temperature-dependent dark current-voltage measurements were carried out to extract the diode parameters and to determine the dominant conduction mechanisms in the forward- and reverse-bias regions. The heterostructure showed three order of magnitude rectifying behavior with a barrier height of 0.72 eV and ideality factor of 2.16 at room temperature. In the high...
Mechanism and characterization studies on boron carbides deposited by chemical vapor deposition technique Karaman, Mustafa; Özbelge, Hilmi Önder; Sezgi, Naime Aslı; Doğu, Timur (2005-12-02) Boron carbide was produced in an impinging jet CVD reactor from a gas mixture of BCl3, CH4 and H-2. The mass transfer limitations on the reaction kinetics were minimised by the jet impingement on the substrate surface. XPS characterization of the produced deposits revealed a nearly pure boron carbide phase containing small amounts of oxy-boron and oxy-carbon species. After a detailed kinetic study, a reaction model was proposed to predict the rates of boron carbide and dichloroborane formation reactions. In...
