摘要

摘要本研究考虑了能量参数变化的空间周期为十纳米级的双层摩尔石墨烯结构。数值研究了层错向角效应和能隙参数对结构电流-电压特性的影响。通过计算该结构的透射系数，发现出现了能量间隙，其大小取决于各层的错向角。

Transport Characteristics Calculation of Bilayer Graphene with Different Misorientation Angle

Abstract

In this work a bilayer moiré graphene structure with a spatial period of energy parameters change of the ten nanometers order is considered. The layer misorientation angle effect and the energy gap parameter on the current-voltage characteristic of the structure is studied numerically. The transmission coefficients calculation through the structure demonstrates the appearance of energy gaps, the magnitude of which depends on the misorientation angle of the layers.
