Effect of Sr Deficiency on Electrical Conductivity of Yb-Doped Strontium Zirconate.

The effect of Sr-deficiency on microstructure, phase composition and electrical conductivity of SrZrYbO (x = 0.94-1.00) was investigated via X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy and impedance spectroscopy.

Effect of A-Site Nonstoichiometry on Defect Chemistry and Electrical Conductivity of Undoped and Y-Doped SrZrO.

The effect of Sr-nonstoichiometry on phase composition, microstructure, defect chemistry and electrical conductivity of SrZrO and SrZrYO ceramics (SZx and SZYx, respectively; x = 0.94-1.02) was investigated via X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy and impedance spectroscopy followed by distribution of relaxation times analysis of impedance data.
