二维原子晶体的菲涅耳系数

Fresnel coefficients of a two-dimensional atomic crystal

Michele Merano

摘要:

通常,单层二维原子晶体的线性光学性质的实验是通过将其模拟为具有有效厚度的均匀板来解释的。在这里,我通过使用菲涅耳系数来拟合石墨烯光学中最显着的实验,固定石墨烯的表面磁化率和表面电导率。结果表明,菲涅耳系数和平板模型是不等价的。实验表明,菲涅耳系数能够模拟这里分析的整体实验,而平板模型未能预测反射光的吸收和相位。

英文摘要:

In general the experiments on the linear optical properties of a single-layer two-dimensional atomic crystal are interpreted by modeling it as a homogeneous slab with an effective thickness. Here I fit the most remarkable experiments in graphene optics by using the Fresnel coefficients, fixing both the surface susceptibility and the surface conductivity of graphene. It is shown that the Fresnel coefficients and the slab model are not equivalent. Experiments indicate that the Fresnel coefficients are able to simulate the overall experiments here analyzed, while the slab model fails to predict absorption and the phase of the reflected light.
