利用含时密度泛函理论研究了入射能量对单层和双层石墨烯的电子透射率的影响。在一定的入射电子能量下，两种叠层结构的BLG的透射率出现了意想不到的交叉。与典型的BLG相比，具有减小或增加的层距离的BLG的行为被保留。我们确定了起源的交叉调查透射电子衍射图案SLG。
Incident-energy-dependent electron transmittances through single-layer graphene (SLG) and bilayer graphene (BLG) were investigated using time-dependent density functional theory. The transmittances of BLG with two kinds of stacking exhibit an unexpected crossing at a certain incident electron energy. The behavior is preserved for the BLG with reduced or increased layer distances compared to that of typical BLG. We determined the origin of the crossing by investigating transmission electron diffraction patterns for SLG.
