Effect of the oxidation states on the electrical properties of Fe-doped Pr2Zr2O7 pyrochlore
Elsevier (2022-01-01)Pyrochlores with formula Pr2Zr2-xFexO7±d (x ¼ 0.00, 0.05, 0.10 and 0.15) were synthesized by the coprecipitation method. Pellets of these compositions sintered at 1400 C for 12 h were characterized by XRD, Rietveld ... -
Enhanced conductivity and nonlinear voltage–current characteristics of nonstoichiometric BaTiO3 ceramics
Wiley-Blackwell (2011-03-21)The electrical conductivity of both BaO-deficient and TiO2-deficient BaTiO3 ceramics shows nonohmic, low-field characteristics at temperatures >∼200°C in contrast to stoichiometric BaTiO3 for which the electrical conductivity ... -
Hole conductivity and acceptor density of p-type CuGaO2 nanoparticles determined by impedance spectroscopy: The effect of Mg doping
Elsevier (2013)Delafossite materials like CuGaO2 have appeared as promising p-type semiconductor materials for their exploitation in tandem dye sensitized solar cells and water splitting photoelectrochemical cells. However, the intrinsic ... -
Probing Lithiation Kinetics of Carbon-Coated ZnFe2O4 Nanoparticle Battery Anodes
American Chemical Society (2014-03)The investigation of the lithiation-delithiation kinetics of anodes comprising carbon-coated ZnFe2O4 nanoparticles is reported in here. The study confirmed that, as occurring with other conversion electrodes, lithiation ...
