Possible realization of hyperbolic plasmons in a few-layered rhenium disulfide

Abstract

The in-plane structural anisotropy in low-symmetric layered compound rhenium disulfide (${\text{ReS}}_2$) makes it a candidate to host and tune electromagnetic phenomena specific for anisotropic media. In particular, optical anisotropy may lead to the appearance of hyperbolic plasmons, a highly desired property in optoelectronics. The necessary condition is a strong anisotropy of the principal components of the dielectric function, such that at some frequency range, one component is negative and the other is positive, i.e., one component is metallic, and the other one is dielectric. Here, we study the effect of anisotropy in ${\text{ReS}}_2$ and show that it can be a natural material to host hyperbolic plasmons in the ultraviolet frequency range. The operating frequency range of the hyperbolic plasmons can be tuned with the number of ${\text{ReS}}_2$ layers.
