(a)–(f) Band structures of epitaxial silicene on various metallic Ir, Pt, Au, Mg, Al, Cu surfaces. (g)–(m) Band structures of epitaxial silicene on metals with K atoms intercalation. E _f is set to be zero. The red color indicates the states contributed from the Si atoms, and its thickness is related to the Si atom characteristic. Black squares in panels (g)–(m) indicate those states contributed from the π ( π *) bands of silicene (Reproduced with permission from Ref. [ 46 ]. Copyright 2014 Nature Publication Group).
