Fig. 3

Large-field views (up) and corresponding zoom-in views (below) of the marked regions in red or yellow squares along the [001] direction taken at (a), room temperature, (b), 300 °C and (c), 500 °C. Red and yellow arrows indicate the position of Ba deficiency. Scale bar: 2 nm (top) and 1 nm (bottom).
