Persistent structural distortions and absent superconductivity in trilayer nickelate thin films

Abigail Y. Jiang, Maria Bambrick-Santoyo, Lopa Bhatt +14

A new family of high-temperature superconductors was recently discovered in the $n=2,3$ Ruddlesden-Popper nickelates, where superconductivity emerges concomitant with suppression o…
