  We investigate the realization of a topological superconductor in a generic
bucked honeycomb system equipped with four types of mass-generating terms,
where the superconductor gap is introduced by attaching the honeycomb system to
an $s$-wave superconductor. Constructing the topological phase diagram, we show
that Majorana modes are formed in the phase boundary. In particular, we analyze
the honeycomb system with antiferromagnetic order in the presence of
perpendicular electric field $E_{z}$. It becomes topological for
$|E_{z}|>E_{z}^{\text{cr}}$ and trivial for $|E_{z}|<E_{z}^{\text{cr}}$, with
$E_{z}^{\text{cr}}$ a certain critical field. It is possible to create a
topological spot in a trivial superconductor by controlling applied electric
field. One Majorana zero-energy bound state appears at the phase boundary. We
can arbitrarily control the position of the Majorana fermion by moving the spot
of applied electric field, which will be made possible by a scanning tunneling
microscope probe.
