From Goldene to Noblene: exhaustive enumeration of the ordered Au-Ag-Cu monolayer alloys

Two-dimensional metals became a laboratory reality with the isolation of Goldene, a gold sheet one atom thick released by chemical exfoliation, which raises the question of what alloying can achieve on the same close-packed lattice.
