摘要: In this chapter, we discuss the physical properties of free-standing silicene . Silicene is a single atomic layer silicon much like graphene. The interest in exactly same as that for graphene, being two-dimensional and possessing Dirac cone One advantage relies on its possible application electronics, whereby natural compatibility with current Si technology might make fabrication more commercial reality. Since has not yet been made, all results are theoretical nature, though most expected to differ significantly substrate.
