Nanotwins in BaTiO₃nanocrystals

Philosophical Magazine A, 1998
Abstract BaTiO3 nanocrystals, in which the coexistence of the high-temperature hexagonal phase with the cubic—tetragonal phase at room temperature was suggested in a previous study, have been investigated using high-resolution transmission electron microscopy.

Nanoporous BaTiO₃ Crystallites

Chemistry of Materials, 2009
Morphology modification of ferroelectric materials at the nanoscale is an important aspect for further development of ferroelectrics. In this work, the synthesis of nanoporous barium titanate prepared under the assistance of Pluronic PE 10300 block copolymer is reported.

Beam modulated fanning in a crystal BaTiO 3

SPIE Proceedings, 2011
Communication systems require devices that allow rapid distribution of signals to multiple users. We presented a proposal for a demultiplexer based on the fanning effect. Beam fanning is a process similar to two-beam coupling, except in this case, in where only one beam is incident on the material and its energy is transferred into scattered light ...

Codoping of Ni and Fe in tetragonal BaTiO 3

Computational Condensed Matter, 2017
Abstract Density functional theory and generalized gradient approximation including a Hubbard-like term were used in the present investigation of tetragonal barium titanate crystal codoped with Ni and Fe impurities. Ubiquitous in any oxide material oxygen vacancy defect has been considered as well.

Thermoluminescence of BaTiO₃crystals

Journal of Physics C: Solid State Physics, 1982
A study of the thermoluminescence (TL) of BaTiO3 samples, X-irradiated at 20K, is presented. The dependence of TL on crystal purity and irradiation dose has been obtained. The variation of the absorption spectrum during thermal annealing and its relation with TL peaks has been investigated. Moreover, the spectral composition and kinetic order of all TL
