Silicene transistors— A review |
(a) Schematics of silicene and its synthesis–transfer fabrication process. (b) Drain current I d versus gate voltage V g curve displays the ambipolar electron–hole symmetry expected from silicene. (c) R versus gate overdrive voltage ( V g– V Dirac) of the silicene device. Measured transfer characteristics (dots) are in good agreement with a widely used ambipolar diffusive transport model (line). Reproduced with permission from Ref. [ 40 ].
