Study on bi-layered ceramics powders prepared by the mechanochemical synthesis
(Elsevier Science Sa, Lausanne, 2009)
Bi-layered structured ferroelectric materials-bismuth titanate, Bi4Ti3O12 (BIT) and barium-bismuth titanate, BaBi4Ti4O15 (BBT) powders were prepared by homogenization and sintering of mixture of stehiometric quantities of ...
Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramics
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
Positive influence of Sb doping on properties of di-phase multiferroics based on barium titanate and nickel ferrite
(Elsevier Science Sa, Lausanne, 2018)
Multiferroic composite materials based on antimony doped barium titanate/nickel ferrite were prepared by a mixing route. In order to obtain fine grained microstructure composite materials, pure constituent phases were ...
Interdependence between structure and electrical characteristics in Sm-doped barium titanate
(Elsevier Science Sa, Lausanne, 2017)
Conventional solid-state method was used to prepare powders of pure and barium titanate (BT) doped with different concentration of samarium. Influence of samarium addition on the structure modification, grain growth ...
Surface optical phonons in ZnO(Co) nanoparticles: Raman study
(Journal of Alloys and Compounds, 2012)
Surface optical phonons (SOP) were observed in the range of 496–572 cm−1 on Raman scattering spectra of nanocrystalline samples of ZnO(Co) prepared by use of the microwave assisted hydrothermal synthesis and traditional ...
Optical properties and plasmon – Two different phonons coupling in ZnGeAs2 + Mn
(Journal of Alloys and Compounds, 2013)
Optical properties of p-type Zn1−xMnxGeAs2 for 0 ⩽ x ⩽ 0.078 were investigated by Raman spectroscopy at room temperature. Phonons of ZnGeAs2 are experimentally determined and they are in excellent agreement with those ...
