Pixel array application of high temperature superconducting YBCO transition edge infrared bolometers
(Izmir Institute of Technology, 2009)
In this thesis, we patterned pregrown epitaxial YBCO thin films on MgO, LAO and STO substrates into meander shaped high-Tc superconducting transition edge monolithic bolometers. We set up and automatized the electrical ...
Growth and characterization of aluminum doped transparent and conductive zinc oxidethin flims
(Izmir Institute of Technology, 2010)
This thesis focuses on fabrication, characterization and understanding physical properties of transparent and conductive Al doped zinc oxide (ZnO) thin films. Films were deposited by magnetron sputtering technique, using ...
Investigation of magnetic dead layer formation at the interfaces of sputtered Ni80 Fe20 thin films
(Izmir Institute of Technology, 2009)
In this thesis, magnetic dead layer formation at the interfaces of the sputtered Ni80Fe20 thin films has been investigated experimentally. Different insulators such as Ta2O5, Al2O3 and metallic Ta thin films have been ...
Improvement of transparent conductive hybrid ITO/Ag/ITO electrodes by electro-annealing
(Izmir Institute of Technology, 2019-07)
The optical and electrical performances of hybrid ITO/Ag/ITO (IAI) layer
structures have been investigated as a function of the Ag and ITO film thicknesses. The
IAI films have been prepared by dc magnetron sputtering at ...
MgB2 superconducting thin films grown by magnetron sputtering
(National Institute of Optoelectronics, 2007-02)
In this study, we report the growth and properties of MgB2 thin films on polycrystalline Al2O3 substrates. A composite MgB2 target was produced by MgB2 and Mg powder mixing, using a hot pressing technique. MgB2 thin films ...
Sub-bandgap optical absorption spectroscopy of hydrogenated microcrystalline silicon thin films prepared using hot-wire CVD (Cat-CVD) process
(Elsevier, 2006-04)
Hydrogenated microcrystalline silicon (μc-Si:H) thin films with different silane concentration (SC) have been prepared using the HW-CVD technique. Dual beam photoconductivity (DBP), photothermal deflection spectroscopy ...
Development of a novel active packaging system based on layer-sy layer deposition of natural antioxidants and antimicrobials to extend food products' shelf life
(Izmir Institute of Technology, 2017-07)
In recent years, Layer-by-Layer (LbL) assembly of thin films has been extensively investigated for many purposes, particularly for its functionality and simplicity of fabrication. Through LbL assembly; antioxidant agents ...
Development of thin film composite nanofiltration membranes with layer by layer polyelectrolyte deposition
(Izmir Institute of Technology, 2017-07)
Nanofiltration (NF) membranes are usually prepared in thin film composite
(TFC) structure through polymerization of various monomers or coating of previously
synthesized polymer on porous support membranes. Layer by layer ...
Production and characterization of HfO2 high-k dielectric layers by sputtering technique
(Izmir Institute of Technology, 2010)
HfO2 thin films have been deposited on Si by in-situ spectroscopic ellipsometric sputtering technique. The grown films have been examined by various diagnostic and analysis techniques (Spectroscopic Ellipsometer (SE), FTIR, ...
Magnetron sputtering growth of AZO/ZnO/Zn(O,S) multilayers for Cu2ZnSnS4 thin film solar cells: Material and device characterization
(Izmir Institute of Technology, 2017-06)
Cu2ZnSnS4 (CZTS) absorber layer attracts so much attention in photovoltaic
industry since it contains earth abundant, low cost and non-toxic elements contrary to
other chalcogenide based solar cells such as CuInGa(S,Se)2 ...
