Silicene vs. ordered 2D silicide: the atomic and electronic structure of the Si-$(\sqrt{19}\times \sqrt{19})R23.4^{\circ }$/Pt(111) surface reconstruction

Martin Svec, Prokop Hapala, Martin Ondracek +8

We discuss the possibility of a 2D ordered structure formed upon deposition of Si on metal surfaces. We investigate the atomic and electronic structure of the Si-$(\sqrt{19}\times\…
