Abstract: (1221 Views)
The two-dimensional, transition metals dichalcogenides (TMDC) layers with straight band gaps have created a new horizon in the use of these materials in photonics and electroptics. In this paper, the effects of the thin layer and the effects of the spacer have been investigated. The optical properties of structures are investigated by the transfer matrix method, TMM, in the visible wavelength region. By looking at the optical features of the structure with spacer the absorption increases. We have been able to achieve an absorption above 99% with thickness of plasmonic layer 75 nm and thickness of spacer 33 nm for MoS2 and 40 nm for MoSe2.
