A review on transport characteristics and Bio-sensingapplication of Silicene.

Silicene, a silicon counterpart of graphene, hass been predicted to possess massless Dirac fermions.
Compared to graphene, the effective spin-orbit interaction is quite significant compared to graphene
and as a result, buckling in silicene opens a gap of 1.55 meV at the Dirac point. This band gap can be
further tailored by applying in plane stress, 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 short review, we would like to explore the transport features of the pristine
silicene and its possible nano derivatives. Besides, the recent progress in biosensor 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.
