ResumoAbstract We describe the deviation from the average structure of Bi-based high-temperature superconductors by introducing one single type of cluster that includes the displacement field. These clusters are easily seen in medium-resolution electron microscopy images, and thus their spatial arrangement provides a simple way of characterizing the material, enabling us to relate superconducting properties to the salient features of the crystal structure.
