Spotty superconductivity (IMAGE) Boston College Caption Examining an iron chalcogenide high-temperature superconductor, Boston College physicist Ilija Zeljkovic and an international team of researchers report in Nature Physics that just before the material fully enters the nematic state, electronic nematicity first appears in nanoscale patches on its surface, represented in this image by the dark markings.
