Figure 5: Bi2212 unit cell and Bi2223 modulated supercell. (a) Three-dimensional structure of Bi2212, indicating the main crystallographic directions. In panel (a), you can see that the crystal is depicted twice. In-plane breathing refers to the crystal on the left inside panel (a), whileout-of plane buckling mode refers to the crystal on the right always in panel (a). (b) Several unit cells of Bi2223 are shown, and the effect of the c-axis modulation is visible.
