Hidden crystal flaw upends 40 years of superconductor theory, Warwick scientists find
Advanced 3D imaging reveals patchwork atomic structure in cuprates that may explain performance differences
Scientists at the University of Warwick have discovered that a superconductor studied for four decades does not have the uniform crystal structure long assumed, but instead contains a complex patchwork of atomic arrangements, potentially overturning established theories and opening new avenues for improving superconducting materials.
