石墨烯中无序加宽朗道子带的形状

The shape of disorder broadened Landau subbands in graphene

W. Zhu, Q. W. Shi, X. R. Wang, J. Chen, J. G. Hou

摘要:

数值计算了高均匀磁场和白噪声随机势作用下石墨烯的态密度。无序展宽的零能朗道带具有高斯形状,其宽度与随机势方差和磁场的平方根成正比。Wegner型计算用于证明结果。

英文摘要:

Density of states (DOS) of graphene under a high uniform magnetic field and white-noise random potential is numerically calculated. The disorder broadened zero-energy Landau band has a Gaussian shape whose width is proportional to the random potential variance and the square root of magnetic field. Wegner-type calculation is used to justify the results.
