Designing a perfect surface plasmon resonance absorber based on graphene and hexagonal boron nitride photonic crystal nanorods

Popis výsledku v původním jazyce

In this work, absorbers in the terahertz region based on one-dimensional photonic crystal nanorods coated with phosphorene, phosphorene-graphene, and phosphorene-hexagonal boron nitride layers were designed. On addition of a graphene layer to the structure, strong localized surface plasmon resonance was observed in two different plasmonic modes via two significant peaks at wavelengths of 10.09 &amp; mu;m and 12.47 &amp; mu;m. The absorption of the structure was affected by the presence of an antireflection layer, and the two modes showed an absorption rate of 99% at wavelengths of 9.72 &amp; mu;m and 9.86 &amp; mu;m, increasing the absorption band to 0.54 &amp; mu;m full width at half maximum. By our changing the dielectric environment with a higher refractive index, better localization and greater absorption occurred. Furthermore, a perfect absorber with two absorption peaks at wavelengths of 11.39 &amp; mu;m and 14.02 &amp; mu;m with 99% and 97% absorption and full width at half maximum of 0.35 &amp; mu;m and 1.1 &amp; mu;m, respectively, was created. Finally, a perfect absorber with an absorption bandwidth of 2.1 &amp; mu;m was obtained in the structure in which hexagonal boron nitride had been placed as a spacer between the monolayers of phosphorene.
