We present a theoretical study of the electronic structure of modulated graphene in the presence of a perpendicular magnetic field. The density of states and the bandwidth for the Dirac electrons in this system are determined. The appearance of unusual Weiss oscillations in the bandwidth and density of states is the main focus of this work.
我们给出了在垂直磁场存在下调制石墨烯电子结构的理论研究。确定了该系统中狄拉克电子的态密度和带宽。带宽和态密度中出现的异常魏斯振荡是本工作的主要重点。
