Researchers from Tokyo Metropolitan University have uncovered clues to understanding the behavior of high-entropy metal telluride superconductors. They found that features typical of glasses, solids with an amorphous structure, and "blurry" electronic states, induced by disorder in the atomic structure, were involved in the unique pressure dependence of the critical temperature where superconductivity arises. This might point to coupling between electrons and vibrations in the atomic lattice, giving rise to exotic superconductivity mechanisms. The research is published in the journal Materials Today Physics.
