Silicene transistors— A review |
(a)–(c) Band structures of silicene around E f at three different vertical electric fields. Inset in panel (a): band structures in the first Brillouin zone at E ⊥ = 0. The Fermi level or the valence band top is set to zero. (d) Dependence of band gap and charge transfer on the electric field. Adapted with permission from Ref. [ 10 ].
