O. Oliveira, A. J. Chaves, W. de Paula, T. Frederico

摘要:

利用弯曲空间中的狄拉克方程研究了变形石墨烯沿给定方向的光透射率。我们对透光率的可用实验数据的理论分析表明,与在无应变石墨烯中观察到的平面外变形相关的周期性波纹解释了这些观察结果。此外,实验单轴应变石墨烯的光透射率显示两个功能,即修改的$\cos^2θ$法律和减少的振幅的振荡与偏振角$θ$,这可以很好地容纳在这里使用的理论分析,并提供进一步的证据,使用QFT在弯曲空间的有效性,以了解二维材料。

英文摘要:

The Dirac equation in curved space is used to study the optical transmittance of deformed graphene along a given direction. Our theoretical analysis of the available experimental data for the light transmittance suggests that the periodic ripple associated with the out-of-plane deformation observed in unstrained graphene explains the observations. Furthermore, the experimental uniaxial strained graphene for light transmittance show two features, namely the modification of the $\cos^2θ$ law and the decrease of the amplitude of the oscillations with the polarization angle $θ$, which can be well accommodated within the theoretical analysis used here and provide further evidence of the validity of using QFT in curved space to understand two dimensional materials.
