Free-standing silicene, a silicon analogue of graphene, has a buckled honeycomb lattice 1 and, because of its Dirac bandstructure 2, 3 combined with its sensitive surface, offers the potential for a widely tunable two-dimensional monolayer, where external fields and interface interactions can be exploited to influence fundamental properties such as bandgap 4 and band character 5 for future nanoelectronic devices 6, 7. The quantum spin Hall effect 3, chiral superconductivity 8, giant magnetoresistance 9 and various exotic field-dependent states 7 have been predicted in monolayer silicene. Despite recent progress regarding the epitaxial synthesis of silicene 8, 9, 10 and investigation of its electronic properties 11, 13, 14, 15, to date there has been no report of experimental silicene devices because of its air stability issue 16. Here, we report a silicene field-effect transistor, corroborating theoretical expectations …
