Figure 1: Crystal structure analyses of SrCo0.8Nb0.1Ta0.1O3−δ (SCNT) at room temperature.
From: A niobium and tantalum co-doped perovskite cathode for solid oxide fuel cells operating below 500 °C
Joint Rietveld refinement plot of SCNT powders at room temperature using both neutron powder diffraction (a) and X-ray powder diffraction data (b). Data are shown as black dots, the calculation as a red line, and the difference between these two as a green line. (c) High-resolution transmission electron microscopy bright field images of SCNT with selected area electron diffraction are shown as insets, along the [01−1] direction on the left and the [011] direction on the right. Scale bar, 10 nm.
