Query: Spin-polarization control driven by a Rashba-type effect breaking the
  mirror symmetry in two-dimensional dual topological insulators   Three-dimensional topological insulators protected by both the time reversal
(TR) and mirror symmetries were recently predicted and observed.
Two-dimensional materials featuring this property and their potential for
device applications have been less explored. We find that in these systems, the
spin-polarization of edge states can be controlled with an external electric
field breaking the mirror symmetry. This symmetry requires that the
spin-polarization is perpendicular to the mirror plane, therefore, the electric
field induces spin-polarization components parallel to the mirror plane. Since
this field preserves the TR topological protection, we propose a transistor
model using the spin-direction of protected edge states as a switch. In order
to illustrate the generality of the proposed phenomena, we consider compounds
protected by mirror planes parallel and perpendicular to the structure, e.g.,
Na$_3$Bi and half-functionalized (HF) hexagonal compounds, respectively. For
this purpose, we first construct a tight-binding effective model for the
Na$_3$Bi compound and predict that HF-honeycomb lattice materials are also dual
topological insulators.
