Figure 4: OpD Bi2223 and UD Bi2212 diffraction patterns and Bragg peaks. (a) Diffraction pattern of optimally doped Bi2223. The electron beam is parallel to the (110) direction. (b) Cut along the (nn0) direction of Bi2223. (c) Diffraction pattern of under-doped Bi2212. The electron beam is parallel to the (110) direction. (d) Cut along the (nn0) direction of under-doped Bi2212. All Bragg peaks are indexed.
