Universal Substrate Effect on the Superconductivity of FeSe Monolayer Films

Slavko Rebec, Tao Jia, Chaofan Zhang +4

To elucidate the mechanisms behind the enhanced $T_c$ in monolayer (1ML) FeSe on SrTiO${}_3$ (STO), we grew highly strained 1ML FeSe on the rectangular (100) face of rutile TiO${}_2$,…
