Periodic table. The metals with fcc and hexagonal structure are indicated. The corresponding (111) or (0001) surfaces have hexagonal symmetry. The crystal structure is indicated (in red), while the relative lateral lattice constant compared with that of silicene is given as a (blue) number in per cent. The elements in red squares form silicides. Reproduced with permission from Ref. [ 22 ] (Copyright 2014 Institute of Physics).
