Possible Liquid-Nitrogen-Temperature Superconductivity Driven by Perpendicular Electric Field in the Single-Bilayer Film of La${}_3$Ni${}_2$O${}_7$ at Ambient Pressure

Zhi-Yan Shao, Jia-Heng Ji, Congjun Wu +2

Recently, high-temperature superconductivity (HTSC) is found in the La${}_3$Ni${}_2$O${}_7$/SrLaAlO${}_4$ ultrathin film with critical temperature $T_c$ above the McMillan limit at ambient…
