Figure 1
(a) Reciprocal-space map and (b) the corresponding peak profile of the 002 reflection at room temperature. The horizontal axis of (a) is the direction of the ω–2θ scan (direction of the diffraction vector), and the vertical axis of (a) is the offset in the ω-scan direction [∊ = (2θ /2) − ω]. The map was taken at the bisecting setting, i.e. ω = θ. The color scale is logarithmic to base 10. |
