Sol-gel-derived thin films of Pb(Zr 0.53 Ti 0.47 )O 3 (PZT) were spin-coated onto the (100)-textured LaNiO 3 (LNO) electrode which was deposited on a Pt/Ti/SiO 2 /Si substrate by rf magnetron sputtering at 350° C. The annealing temperature for obtaining a perovskite PZT film on LNO was reduced by about 50° C compared…

Pb(Zr x Ti 1- x )O 3 (PZT) thin films were prepared on Ir/IrO 2 and Pt/IrO 2 electrodes. We have already reported that fatigue properties of PZT thin films were improved by using these electrodes due to barrier effects of IrO 2 . In this present paper we describe a study of the imprint characteristics of PZT thin film…

We report the crystalline quality and electrical properties of PbZr x Ti 1- x O 3 (PZT) films grown on Si substrates with a SrTiO 3 (STO) buffer layer. STO buffer layers and PZT films were formed on Si substrates by the electron-beam assisted vacuum evaporation technique and the sol-gel technique, respectively. It is…
SrTiO 3 thin films are deposited on Pt/SiO 2 /Si substrates using RF magnetron sputtering in a temperature range from 200° C to 600° C. The film deposited at 600° C shows the best dielectric property and leakage current characteristics due to its good crystallinity and stoichiometric composition. Dielectric constant o…
Angle-dependent conduction-electron spin resonance and static magnetic-susceptibility measurements of bulk, aligned, and partially purified carbon nanotube films show anisotropies reflecting the anisotropic character of the tubes. The Pauli susceptibility (above 40 K) of the tubes corresponds to about ${10}^{18}$ spin…
We have developed the series of thin-film bismuth layer structured ferroelectric (BLSF) materials such as SrBi 2 Ta 2 O 9 , SrBi 2 Nb 2 O 9 , SrBi 4 Ti 4 O 15 and their solid solutions using metallo-organic-decomposition (MOD) spin-on coating techniques. We found that SrBi 2 Ta 2 O 9 is one of the best potential candi…

Abstract The local structure of CH 3 NH 3 I around the I - ion in Phase α' and δ was studied by iodine K-edge EXAFS. The crystal structure in Phase α' was redetermined by single crystal X-ray diffraction. The Debye-Waller factor σ (2) derived from EXAFS spectra shows an anomalous behavior around the order-disorder tra…
The composite containment proposed aims to cope with beyond-design-basis accidents. The goal is to restrict the consequences of severe core meltdown accidents to the reactor plant. One essential of this new concept is passive decay heat removal from the containment by natural air convection.Experimental and calculatio…
Abstract This investigation focused on the study of dynamic mechanical losses in silica-filled networks of poly(dimethylsiloxane) (PDMS). Some of the samples were filled using a novel method, specifically the in situ precipitation of particulate silica either after or during network formation. Others were filled using…
Superplasticity of Ti-6Al-4V alloy specimens prepared by various routes of thermomechanical processing was evaluated by high temperature tensile tests. It was found that, to maximize superplasticity, the material should first be solution treated at 1050 °C and quenched into water to obtain needle-like a' martensite, a…
The rolling‐contact fatigue life and wear of CVD‐SiC coatings with surface compression were studied using a three‐ ball‐on‐rod rolling‐contact fatigue (RCF) tester. Two levels of surface compression in the coatings, approximately 190 μm thick, were introduced by using substrates of a liquid‐phase sintered SiC and a Si…
