  At the domain wall between two regions with the opposite Chern number, there
should be the one-dimensional chiral states, which are called as the kink
states. The kink states are robust for the lattice deformations. We design a
multi-terminal device with the kink states to study the local Andreev
reflection and the crossed Andreev reflection. The coefficient of the crossed
Andreev reflection can reach 1 in the four-terminal device. Besides adjusting
the phase difference between superconductors, the local Andreev reflection and
the crossed Andreev reflection can be controlled by changing the on-site energy
and the stagger energy in the four-terminal device. Our results give some new
ideas to design the quantum device in the future.
