石墨烯磁波导中的电导量子化和蛇态

Conductance quantization and snake states in graphene magnetic waveguides

T. K. Ghosh, A. De Martino, W. Häusler, L. Dell'Anna, R. Egger

摘要:

我们考虑电子波导(量子线)在石墨烯创建适当的非均匀磁场。讨论了单向蛇态的性质。对于特定的磁场分布,形成两个空间上分离的反向传播蛇态,导致电导量化对磁场的杂质或不规则性的反向散射不敏感。

英文摘要:

We consider electron waveguides (quantum wires) in graphene created by suitable inhomogeneous magnetic fields. The properties of uni-directional snake states are discussed. For a certain magnetic field profile, two spatially separated counter-propagating snake states are formed, leading to conductance quantization insensitive to backscattering by impurities or irregularities of the magnetic field.
