Y. Matsui, H. Maeda, Y. Tanaka, S. Horiuchi, "Possible model of the modulated structure in high-Tc superconductor in a Bi-Sr-Ca-Cu-O system revealed by high-resolution electron microscopy," Japanese Journal of Applied Physics, 27 (3), L372-L375, March 1988.

Yoshio Matsui and Hiroshi Maeda (National Research Institute for Metals, Tsukuba Laboratory, Ibaraki, Japan): "We found, for the first time, an anomalously big (up to 20%) modulated layer structure in this high Tc superconducting compound. This helps explain the mechanism of superconductivity because all super- conducting bismuth compounds have this structure. Another reason our paper may have been highly cited is that the quality of our photographs of the compound taken by a high resolution electron microscope is remarkably good."
