Monolayer Kagome metals AV3Sb5

Abstract

Much recent work has focused on the kagome metals AV3Sb5 (A = K, Rb, and Cs), but studies of the monolayer form are only just beginning. Here, the authors theoretically study monolayer kagome metals, and predict modified van Hove singularities that lead to charge-density-wave doublets and d-wave superconductivity.
