Optical Transmission Enhancement of MoS<sub>2</sub> Nanosheets Doped with Magnetic Materials Ni, Mn, and Cr

Abstract

In this work, we report both theoretical and experimental study of the influence of some materials with magnetic aspects such as Ni, Mn, or Cr in MoS2 photonic crystal structures. A functional density method technique has been introduced. Indeed, the results indicated that the transmission spectrum is considerably affected by the impact of doping from a photo shape and amplitude. Furthermore, appropriate doping has been shown to change the peak transmission shape of the MoS2 photonic crystal by splitting as an example. In fact, the transmission spectrum remains less identical with Ni and Mn doping and exhibits a doubling peak with Cr attributed to the first and second waveguide propagation modes. The obtained results can give a new degree of freedom in device application of MoS2 nanosheets such as photonic sensors, filter, and reflector. Finally, we can predict that the MoS2 photonic crystal doped with magnetic materials could be used in applications involving plasmonic Fano-resonances.
