摘要

二维过渡金属钙钛矿（TMC）具有很强的电子极化性和更高的介电损耗，因此作为频率选择性吸收体（FSA）具有很高的利润。在本研究中，我们开发了由 NiSe2、CoSe2 等二维过渡金属钙钛矿制成的油墨，并利用它们开发了具有高反射损耗的转移结构。这些结构的电导率峰值取决于涂料中二维结构的浓度。据观察，吸收带宽和频率似乎取决于二维 TMC 的成分和所制作的结构。这为调节 FSA 性能提供了一种新方法。

2D materials-based ink to develop meta-structures for electromagnetic interference (EMI) shielding

2-D transition metal-chalcogenides (TMCs) are lucrative as frequency selective absorbers (FSAs) because of strong electronic polarization and enhanced dielectric loss. In the present work we have developed inks made of 2-D TMCs such as NiSe₂, CoSe₂ and used them to develop metastructures having high reflection loss. The structures have conductivity peaks depending on concentration of the 2D structure in the paint. It is observed that the absorption bandwidth and frequency seem to depend on the composition of 2D TMC along with the structures made. This provides an additional method to modulate the properties of FSA.
