Superconductivity in infinite-layer nickelate La${}_{1-x}$Ca${}_x$NiO${}_2$ thin films

S. W. Zeng, C. J. Li, L. E. Chow +8

We report the observation of superconductivity in infinite-layer Ca-doped LaNiO${}_2$ (La${}_{1-x}$Ca${}_x$NiO${}_2$) thin films and construct their phase diagram. Unlike the metal-insulat…
