  Transverse electric (TE) surface wave in silicine is theoretically
investigated. The TE surface wave in silicene is found to exhibit better
characteristics compared with that in graphene, in terms of a broader frequency
range and more confinement to the surface which originate from the buckled
structure of silicene. We found that even undoped silicene can support the TE
surface wave. We expect to obtain the similar characteristics of the TE surface
wave in other two-dimensional materials that have slightly buckled honeycomb
lattice.
