In piezoelectric market, infrared detectors, pyroelectric and piezoelectric sensors, microwave devices, actuators, transducers, non-volatile random access memories, and micro electromechanical systems are fabricated using lead zirconate titanate (PZT) based films. These films are deposited by chemical vapor deposition, physical vapor deposition spin coating, screen printing and electrospray deposition (ESD) technique. Among them, ESD is the most preferred method because of its high material efficiency, simplicity of experimental set up, wide choice of precursor and low cost. Therefore, the purpose of this study is to fabricate and characterize the ESD deposited PZT films. In our study, Pb(Zr0.Ti-52(0.48))O-3 (PZT) nano powders (Nanotech Corp. Turkey) and MMC PZT sol (Mitsubishi Corp. Japan) combinations were mixed in various concentrations. Prepared composite PZT slurries were coated with ESD technique. Fabricated PZT thick films were characterized with scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray diffraction method (XRD) to evaluate surface and crystal structure of the films. The results show that, MMC sol and PZT nanopowder combinations provide smooth and homogeneous film surface., dense and non-cracked film microstructure was observed using excess PbO during sintering.

GROWTH, CHARACTERIZATION AND DEVICE APPLICATIONS OF CADMIUM ZINC TELLURIDE THIN FILMS Doğru Balbaşı, Çiğdem; Parlak, Mehmet; Department of Physics (2022-5-25) CdZnTe is an II-VI group semiconductor material with significant properties used in many critical industrial applications, such as photovoltaic devices, photodiodes, photoconductors, room temperature gamma-ray spectroscopy, X-ray imaging, and infrared detectors. In Particular, CdZnTe is a promising material for solar cell application as an absorber layer due to its direct tunable bandgap property, high atomic number with strong absorption, excellent optoelectronic properties, and long-term stability. Howeve...
Structural and electronic properties of lithium endohedral doped carbon nanocapsules Pekoz, Rengin; Erkoç, Şakir (Elsevier BV, 2007-02-01) Endohedral lithium and lithium ion doped carbon nanocapsule (CNC) systems have been theoretically investigated by performing semi-empirical molecular orbital method at the level of PM3 (UHF and/or RHF) type quantum chemical treatment in order to explore the energetics and electronic structures. The geometries of the studied systems have been optimized and the molecular properties, energies, some selected molecular orbital eigenvalues and dipole moments of the studied capsules are reported. Molecular dynamic...
Structural and electrical analysis of poly-Ge films fabricated by e-beam evaporation for optoelectronic applications Kabacelik, Ismail; KULAKCI, MUSTAFA; Turan, Raşit (2016-12-01) We have investigated the relationship between structural and electrical properties of Ge thin films deposited on single crystal silicon (100) substrates by electron beam evaporation at room temperature. Post-thermal annealing was applied to obtain poly-crystalline Ge thin films. The structural effects of the annealing temperature and annealing time on the crystallization of Ge films were analyzed using Raman and X-ray diffraction measurements. Raman and X-ray diffraction spectra revealed a structural evolut...
Structural and molecular electronic properties of B-N ring doped single-wall carbon nanotubes Malcıoğlu, Osman Barış; Erkoc, A (Elsevier BV, 2005-08-01) Various molecular electronic properties of boron-nitride nanotube ring doped four different single-wall carbon nanotubes are investigated theoretically by performing self-consistent-field molecular-orbital semi-empirical and density functional theory calculations. Results are compared with corresponding carbon nanotubes. It is seen that polar nature of the boron-nitride nanotube ring lead to a spontaneous polarization, an electrostatic potential barrier occurs in metallic carbon nanotube models, and these m...
Structural, electrical and optical characterization of ge-implanted gase single crystal grown by Bridgman Method Karaağaç, Hazbullah; Akınoğlu, Bülent Gültekin; Department of Physics (2005) In this work, structural, electrical and optical characterization of as-grown, Ge-implanted, and annealed GaSe single crystals grown by using 3-zone vertical Bridgman-Stockbarger system, have been studied by carrying out X-ray Diffraction (XRD), electrical conductivity, Hall effect, photoconductivity, and spectral transmission measurements. The temperature dependent electrical conductivity of these samples have been measured between 100 and 400 K. As a result, it was observed that upon implanting GaSe with ...
