Micropatterning of Pb(Zr0.52Ti0.48)O-3 (PZT) thin films with line features as small as 350 nm was demonstrated through capillary molding of organometallic solutions within the continuous channels of an elastomeric mold. Despite the large stresses that develop during the evaporation of the solvent, pyrolysis of the organics, and the densification and crystallization of the inorganic gel, the patterned crystalline PZT films were crack-free and mechanically robust. Flawless regions as large as I cm(2) were obtained. The cross-sectional shape of the patterned PZT lines was trapezoidlike. Single perovskite PZT grains that formed during annealing at 600-700 degreesC completely filled the cross-sectional area of the patterned lines. Lead acetate, zirconium propoxide, and titanium isopropoxide were used as the starting materials. Substrates used included silver tape, stainless steel plate, silicon wafer, and platinum-coated silicon wafer.


Mechanical behaviour of Al2O3-ZrO2 minicomposite reinforced glass matrix optomechanical composite
Dericioğlu, Arcan Fehmi (Informa UK Limited, 2003-08-01)
To understand the effect of a 'mesh-structured reinforcement' on the optical and mechanical properties of optomechanical composites, a unidirectional Al2O3 fibre-ZrO2 matrix minicomposite reinforced glass matrix optomechanical composite has been fabricated. By regular alignment of the minicomposites in the glass matrix as part of the 'mesh structure' a high degree of optical transparency is obtained in the composite; this transparency is proportional to its 'optical window' regions. The mesh structured rein...
Hydrothermal BaTiO3 thin films from nanostructured Ti templates
Akyildiz, Hasan; Casper, Michelle D.; Ayguen, Seymen M.; Lam, Peter G.; Maria, Jon P. (Cambridge University Press (CUP), 2011-02-01)
Polycrystalline BaTiO3 thin films have been prepared by hydrothermal reaction with sputter-deposited nanostructured reactive Ti templates designed to control net diffusion direction and distance. Templates were prepared in two morphologies, i.e., planar and nanopillar. The samples produced from flat templates showed sluggish transformation kinetics and an eventual termination of reaction without fully consuming the Ti metal. Templates with pillar morphology, on the other hand, could be transformed to phase-...
Temperature dependent band gap in SnS2xSe(2-2x) (x=0.5) thin films
Delice, S.; Isik, M.; Gullu, H. H.; Terlemezoglu, M.; Surucu, O. Bayrakli; Hasanlı, Nızamı; Parlak, Mehmet (Elsevier BV, 2020-08-01)
Structural and optical properties of SnS2xSe(2-2x) thin films grown by magnetron sputtering method were investigated for composition of x = 0.5 (SnSSe) in the present study. X-ray diffraction, energy dispersive X-ray spectroscopy, atomic force microscopy and scanning electron microscopy methods were used for structural characterization while temperature-dependent transmission measurements carried out at various temperatures in between 10 and 300 K were accomplished for optical investigations. X-ray diffract...
Optical characteristics of Bi12SiO20 single crystals by spectroscopic ellipsometry
Isik, M.; Delice, S.; Nasser, H.; Hasanlı, Nızamı; Darvishov, N. H.; Bagiev, V. E. (Elsevier BV, 2020-12-01)
Structural and optical characteristics of Bi12SiO20 single crystal grown by the Czochralski method were investigated by virtue of X-ray diffraction (XRD) and spectroscopic ellipsometry measurements. XRD analysis indicated that the studied crystal possesses cubic structure with lattice parameters of a = 1.0107 nm. Spectral dependencies of several optical parameters like complex dielectric constant, refractive index, extinction and absorption coefficients were determined using ellipsometry experiments perform...
Improvement of fracture resistance in a glass matrix optomechanical composite by minicomposite unit bridging
Dericioğlu, Arcan Fehmi (Elsevier BV, 2005-10-15)
Minicomposite unit bridging, which was experimentally determined to be the dominant toughening mechanism resulting in the R-curve behavior of the Al2O3-ZrO2 minicomposite-reinforced glass matrix optomechanical composite, was studied quantitatively using luminescence spectroscopy. Applied stress induced shift of the luminescence bands of the minicomposite reinforcement was calibrated. Using the experimentally obtained calibration curve, axial stresses could be mapped along the minicomposite embedded in the g...
