Dual Enhancement of Superconductivity in FeSe/SrTiO3 via Orbital and Correlation Synergy

Guihao Jia, Jingming Yan, Yucong Peng +5

In iron-based superconductors, the dz2 orbital band typically resides far below the Fermi level and has not been considered to participate in Cooper pairing. Here, using monolayer…
