The integration of semiconductive nano-ZnO into a Ti/Zr-based solution has facilitated the development conductive coating on aluminum alloy surfaces.
Bi 3.25 La 0.75 Ti 3 O 12 (BLT) thin films have been grown on n-type Si (100) substrates by metalorganic decomposition method. The structural properties of the were examined x-ray diffraction. BLT exhibit good insulating property with room temperature resistivities in range 1012–1013 Ω cm. current–voltage characteristics show ohmic conductivity lower voltage and space-charge-limited higher range. capacitance–voltage characteristic hysteresis curves that metal-ferroelectric-semiconductor...
Electrical properties of the interface between Bi4Ti3O12 ferroelectric film and p-Si substrate have been studied by capacitance–voltage (C–V) characteristics. It is found that barrier can be broken down temporally because charge injection from Si into thin film, this behavior induces hump valley structures in C–V curves. also polarization aligned along a preferential direction semiconductor to which attributed ferroelectric/p-Si contact.
Ba 0.8 Sr 0.2 TiO 3 thin films were prepared with various individual layer thicknesses using a sol–gel process. The thickness strongly affected the structure, ferroelectricity, and dielectric properties of films. an 60 nm showed small equiaxed grains, cubic temperature‐independent constant, no ferroelectricity. 8 columnar tetragonal good two peaks in constant–temperature curve. for layer‐by‐layer homoepitaxy growth that resulted grains was <20 nm.
A sol‐gel process was used to prepare pyroelectric Ba 0.8 Sr 0.2 TiO 3 thin films with large columnar grains (100–200 nm in diameter) on Pt/Ti/SiO 2 /Si substrates, via using a 0.05 M solution precursor. The relationship between dielectric constant and temperature (ɛ r ‐ T ) showed two distinctive phase transitions the films. Both remnant polarization coercive field decreased as increased from −73°C 40°C. Its low dissipation factor (tan δ= 2.6%) high coefficient ( p = 4.6 × 10 −4 C·(m ·K) −1...
LaF3/titania nanotube array (TNAs) electrodes were fabricated by electrodeposition of LaF3 on synthesized TNAs. The electrode was characterized scanning electron microscope (SEM), X-ray diffraction (XRD), and energy dispersive spectrometer (EDS). exhibited excellent response to fluoride ion. linear calibration range achieved four orders magnitude F- concentration (10−6–10−2 mg/ml) the sensitivity is higher than that ordinary ion selective (mode PF-1). limit detection (LOD) estimated be 4.39...
BaxSr(1-x)TiO3 (BST) thin films are in situ deposited on a Ti matrix through the micro-arc oxidation technique, using mixed aqueous solution of Ba(OH)2•8H2O, Sr(OH)2•8H2O and 0.05 M EDTA as electrolyte. The influence Ba2+/Sr2+ ratio phase composition, microstructure properties BST is investigated. Ba0.6Sr0.4TiO3, Ba0.5Sr0.5TiO3, Ba0.4Sr0.6TiO3 have cubic phase, while Ba0.8Sr0.2TiO3 Ba0.7Sr0.3TiO3 tetragonal phase. When concentration Ba2+ electrolyte surpasses that Sr2+, width holes surface...
PbFe12O19 (PFO) powders in hexagonal structure have been synthesized by sol-gel process using lead acetate, glycerin and ferric acetylacetonate as the precursor. ceramics were obtained sintering at 1000\degree C for 1 hour. Distorted flaky hexahedron grains are frequently observed SEM images of sintered ceramics. Large spontaneous polarization was ceramic room temperature, exhibiting a clear ferroelectric hysteresis loop. The remnant is estimated to be Pr~21{\mu}C/cm2. distortion well Fe...
