论文摘要
我们表明，大量的diselenide，Rese2的特征是在近红外频率范围内折射率超过5的折射率高值。我们使用背面局灶平面反射光谱来提取RESE2介电常数张量的成分，并揭示其极端的双轴各向异性。我们还证明了实验数据与密度功能理论的预测之间的良好一致性。大型折射率和巨大光学各向异性的组合使RESE2成为近红外频率范围内全型纳米素化学的透视材料。
We show that bulk rhenium diselenide, ReSe2 is characterized by record high value of the refractive index exceeding 5 in near-infrared frequency range. We use back focal plane reflection spectroscopy to extract the components of the ReSe2 permittivity tensor and reveal its extreme biaxial anisotropy. We also demonstrate the good agreement between the experimental data and the predictions of the density functional theory. The combination of the large refractive index and giant optical anisotropy makes ReSe2 a perspective material for all-dielectric nanophotonics in the near-infrared frequency range.
