论文摘要
我们已经研究了假石墨烯中伪冬极化在电子波数据包动力学中的作用，以及受外部磁场的石墨烯解毒晶格中的作用。使用绿色的功能形式主义，我们表明电子动力学可以通过调整伪旋转极化来控制。我们发现，在Landau量化了原始石墨烯中，电子波数据包的传播和Zitterbewegung振荡在很大程度上取决于伪蛋白极化。发现电子波数据包在初始伪旋转极化的方向上传播。我们还表明，在这个系统中，可以通过在该方向上雕刻一个尺寸的解毒剂晶格来在任何期望的方向上增强电子的传播。该研究表明，石墨烯解毒剂晶格可以用作电子传输的通道，并通过伪旋转极化，解毒剂电位和应用正常磁场强度进行可调性。
We have investigated the role of pseudospin polarization in electron wave packet dynamics in pristine graphene and in a graphene antidot lattice subject to an external magnetic field. Employing a Green's function formalism, we show that the electron dynamics can be controlled by tuning pseudospin polarization. We find that in Landau quantized pristine graphene both the propagation of an electron wave packet and Zitterbewegung oscillations strongly depend on pseudospin polarization. The electron wave packet is found to propagate in the direction of initial pseudospin polarization. We also show that, in this system, the propagation of an electron can be enhanced in any desired direction by carving a one dimensional antidot lattice in that direction. The study suggests that a graphene antidot lattice can serve as a channel for electron transport with the possibility of tunability by means of pseudospin polarization, antidot potential and applied normal magnetic field strength.
