In the April 11 issue of the American journal, Science, the results of joint research by CRIEPI, Princeton University, and Osaka University were published, and on April 14, a press release was issued to energy journalists and other relevant parties.

CRIEPI is the only organization in the world with the technology to produce high quality, single crystals of the high-Tc superconductor Bi₂Sr₂CaCu₂O_8+δ, known as bismuth copper-oxide. The article identifies the uneven spatial distribution of superconductivity in a certain type of copper-oxide high-Tc superconductor, using a test method known as tunneling spectroscopy, developed jointly by Shimpei Ono, Research Scientist of the Materials Science Laboratory, a group led by Professor Ali Yazdani of Princeton University, and a group led by Professor Yoichi Ando of Osaka University. This is expected to lead to further progress in clarifying the mechanism behind high-temperature superconductors.
