Interfacial mode coupling as the origin of the enhancement of Tc in FeSe films on SrTiO3

J. J. Lee, F. T. Schmitt, R. G. Moore +11

Single unit cell films of iron selenide (1UC FeSe) grown on SrTiO3 (STO) substrates have recently shown superconducting energy gaps opening at temperatures close to the boiling poi…
