A Comparative Analysis of BaTiO3/(Ba,Sr)TiO3 and BaTiO3/(Ba,Sr)TiO3/SrTiO3 Artificial Superlattices via Raman Spectroscopy [PDF]
Materials Research, 2018 BaTiO3/Ba50Sr50TiO3 and BaTiO3/Ba50Sr50TiO3/SrTiO3 superlattices are characterized via Raman spectroscopy. Special attention is paid to a comprehensive analysis of their polarized Raman spectra, especially, within a soft mode (E(1TO)) range. The shift of

Materials Letters, 2007 Abstract We have investigated the effect of coupling agents with different organic moiety on the dielectric properties of polyimide/BaTiO 3 (70 nm) composite films. INAAT (isopropyl tris( N -amino-ethyl aminoethyl)titanate, KR 44) and APTS (3-amino-propyl-triethoxysilane) were used as coupling agents, respectively, for homogeneous dispersion of ...

Structural studies of BaTiO3:Er3+ and BaTiO3:Yb3+ powders synthesized by hydrothermal method
Journal of Rare Earths, 2014 Erbium and ytterbium doped barium titanate nanopowders were prepared using the hydrothermal method. A barium titanate structure doped with rare earth ions manifested new characteristics and improved the field of application of optical devices such as trichromatic tubes, LCD displays, lamps, and infrared lasers. In this work, BaTiO3:Er3+ and BaTiO3:Yb3+

Ferroelectric Catalysts in the Hydrogen Evolution Reaction: A Perspective. [PDF]
Adv Sci (Weinh)This perspective summarizes recent advances in ferroelectric (FE) catalysts for the hydrogen evolution reaction (HER). It first introduces HER fundamentals and FE mechanisms, then classifies FE catalysts into single‐phase, single‐atom‐modified, heterostructured, and other engineered types, with representative examples.

Magneto-optical properties of BaTiO3/La0.76Sr0.24MnO3/BaTiO3 heterostructures [PDF]
AIP Advances, 2018 The magnetic properties of epitaxial BaTiO3/La0.76Sr0.24MnO3/BaTiO3 (BTO/LSMO/BTO) heterostructures have been studied using magneto-optic Kerr effect (MOKE) technique. Both longitudinal and polar MOKE were probed as a function of magnetic field and temperature (in the range between 80 and 320 K) for epitaxial films of BTO/LSMO/BTO and LSMO grown on ...

Detection of Degraded Formulated BaTiO<sub>3</sub> Induced by Oxygen Vacancy Migration Using Ultrasonic Attenuation. [PDF]
Adv Sci (Weinh)Oxygen vacancy migration is a key degradation mechanism for the majority of MLCCs. There are limitations with spatially identifying regions of a capacitor that have degraded due to oxygen vacancy migration. This work showcases ultrasonic attenuation as a non‐electrical and nondestructive technique of identifying oxygen vacancy degraded regions of an ...

Electrical and Physical Characterization of Bulk Ceramics and Thick Layers of Barium Titanate Manufactured Using Nanopowders [PDF]
, 2007 Fine powders of BaTiO3 are synthesized by hydrothermal processing at 250 C for 7 h. Two different starting mixtures were used, TiCl3 + BaCl2 and TiO2 + BaCl2. The size of the resulting crystallites was close to 20 nm in both cases.
