Crystal disorder offers a different explanation for a superconducting pattern
Cornell researchers report that imperfections in an iron-based material can be central to how its superconductivity changes.
The university’s 17 September account describes a study published in PNAS on 20 August. It examines iron selenide and challenges an explanation based mainly on changing electron numbers. The result concerns a specific material and experimental conditions, not a room-temperature power-grid technology.
