The transport properties of Kekulé-ordered graphene - junctions
Peipei Zhang, Chao Wang, Yu-Xian Li +2
The transport properties of electrons in graphene - junction with uniform Kekulé lattice distortion have been studied using the tight-binding model and the Landauer-Büttiker…
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…
Andreev reflection in a Y-shaped graphene-superconductor device
Chao Wang, Youlian Zou, Juntao Song +1
Using the non-equilibrium Green function method, we study the Andreev reflection in a Y-shaped graphene-superconductor device by tight-binding model. Considering both the zigzag an…
Quantum interference in topological insulator Josephson junctions
Juntao Song, Haiwen Liu, Jie Liu +4
Using non-equilibrium Green's functions, we studied numerically the transport properties of a Josephson junction, superconductor-topological insulator-superconductor hybrid system.…
A controllable valley polarization in Graphene
Yang Liu, Juntao Song, Yuxian Li +2
The electron transport of different conical valleys is investigated in graphene with extended line-defects. Intriguingly, the electron with a definite incident angle can be complet…
Quantum Andreev effect in 2D HgTe/CdTe quantum well-superconductor systems
Qing-feng Sun, Yu-Xian Li, Wen Long +1
The Andreev reflection (AR) in 2D HgTe/CdTe quantum well-superconductor hybrid systems is studied. A quantized AR with AR coefficient equal to one is predicted, which is due to the…
