Abstract:
Silicene, a silicon counterpart of graphene, has been predicted to possess Dirac fermions. The effective spin-orbit interaction in silicene is quite significant compared to graphene; as a result, buckled silicene exhibits a finite band gap of a few meV at the Dirac point. This band gap can be further tailored by applying in plane strain, an external electric field, chemical functionalization and defects. This special feature allows silicene and its various derivatives as potential candidates for device applications. In this topical review, we would like to explore the transport features of the pristine silicene and its possible nano derivatives. As a part of it, Thermoelectric properties as well as several routes for thermoelectric enhancement in silicene are investigated. Besides, the recent progress in biosensing applications of silicene and its hetero-structures will be highlighted. We hope the results obtained from recent experimental and theoretical studies in silicene will setup a benchmark in diverse applications such as in spintronics, bio-sensing and opto-electronic devices.
