Surface electronic structure and isotropic superconducting gap in (Li${}_{0.8}$Fe${}_{0.2}$)OHFeSe

X. H. Niu, R. Peng, H. C. Xu +13

Using angle-resolved photoemission spectroscopy (ARPES), we revealed the surface electronic structure and superconducting gap of (Li${}_{0.8}$Fe${}_{0.2}$)OHFeSe, an intercalated FeSe-…
