Dual instability of superconductivity from oxygen defects in La${}_3$Ni${}_2$O${}_{7+\hat{I}´}$

Peiheng Jiang, Jie Li, Yu-Han Cao +4

We uncover a dual mechanism by which oxygen defects suppress superconductivity in the bilayer nickelate La${}_3$Ni${}_2$O${}_{7+\hat{I}´}$ using density functional theory, dynamical mean-field…
