Resonant dielectric amplification of superconductivity at the FeSe:SrTiOT${}_3$ interface

Krzysztof Kempa, Michael J. Naughton, Hanno H. Weitering

Epitaxial monolayers of FeSe grown on SrTiO${}_3$ (STO) and related polar substrates exhibit superconducting transition temperatures of 65-70 K, far above the ~8 K value of bulk FeSe…
