摘要
最近,通过对晶格形变的显式包含,完善了应变石墨烯中电子的标准描述。在此,我们考虑了这些晶格修正的影响,以找出能在应变石墨烯内部产生均匀赝磁场的机械形变。与之前在矩形几何结构中的提议相比,主要区别在于需要同时拉伸锯齿形(zigzag)边缘和扶手椅形(armchair)边缘。

备注
This paper has been withdrawn by the author since it's based on the equations of strained graphene using the Dirac approach. There is a debate going on concerning the use of these equations, so we prefer to wait until a consensus is reached. We will update this manuscript with some fixes to the strain equations as soon as possible
