论文摘要
在最近的实验中,已经测量了可见光谱中单层二维原子晶体的平面外表面敏感性。这种敏感性为二维材料的反射率提供了可衡量的贡献。在这里,我们对反射特性提供了完整的理论描述,考虑到传入的S和P极化平面波在晶体上的任何入射角,计算局部,反射和传播电磁场。我们最终将显微镜极化性连接到平面内和平面外宏观表面敏感性。
In a recent experiment, the out-of-plane surface susceptibility of a single-layer two-dimensional atom crystal in the visible spectrum has been measured. This susceptibility gives a measurable contribution to the reflectivity of two-dimensional materials. Here we provide a complete theoretical description of the reflective properties, considering incoming s and p polarized plane waves at any angle of incidence on the crystal, computing local, reflected and transmitted electromagnetic fields. We finally connect the microscopic polarizability to both the in-plane and the out-of-plane macroscopic surface susceptibilities.
