Abolhassan Vaezi, Nima Abedpour, Reza Asgari, Alberto Cortijo, María A. H. Vozmediano

摘要:

我们显示了通过在保留时间反转对称性的带隙石墨烯样品中施加时间依赖性应变来诱导边缘电荷电流的可能性。我们证明,这种边缘电流具有相同的起源作为谷霍尔响应已知存在于系统中。

英文摘要:

We show the possibility of inducing an edge charge current by applying time-dependent strain in gapped graphene samples preserving time reversal symmetry. We demonstrate that this edge current has the same origin as the valley Hall response known to exist in the system.
