Abstract
Silicene is a two dimensional material of silicon and has zero-gap semiconductor characteristics as is garaphene, where nnergy dispersion reveals Dirac-Fermion nature.
Moreover, silicene is expected to be very sensitive to electric field due to its buckled structure. In this paper, we discuss the Dirac-Fermion nature of silicene and propose a recipe for synthesis for free-standing silicene by the theoretical approaches.
