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.
