Intravalley Andreev reflection in the multi-terminal device with Y-shaped Kekulé graphene superlattices
Chao Wang, Peipei Zhang, Yu-Xian Li +1
Using the tight-binding model, a multi-terminal superconductor(S) device is proposed, where the structures of the center region are primitive grpahene(G) and Y-shaped Kekulé graphe…

Andreev reflection adjusting in the multi-terminal device with the kink states
Lin Zhang, Chao Wang, Peipei Zhang +1
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 r…

The influence of anti-chiral edge states on Andreev reflection in graphene-superconductor junction
Chao Wang, Lin Zhang, Peipei Zhang +2
Using the tight binding model and the non-equilibrium Green function method, we study Andreev reflection in graphene-superconductor junction, where graphene has two nonequal Dirac…
