This work investigated the effect of B2O3 on phase structure and electrical properties of CuO-modified (Ba0.95Ca0.05)(Ti0.90Sn0.10)O3–0.5CuO–xB2O3 (BCTSCu0.5Bx, 0≤x≤1.8mol.%) lead-free ceramics sintered at a low sintering temperature (Ts=1200°C). It was found that co-doping CuO and B2O3 is effective both on obtaining a dense microstructure and increasing the Curie temperature (TC) in BCTSCu0.5Bx ceramics...
Deposition of high-k HfO2 gate dielectric films on n-type Si and quartz substrates by sol–gel spin-on coating technique has been performed and the structural, optical and electrical characteristics as a function of annealing temperature have been investigated. The structural and optical properties of HfO2 thin films related to annealing temperature are investigated by X-ray diffraction (XRD), ultraviolet–visible...
