Abstract
We reveal the feasibility of the localized surface plasmon resonance in a system of Bi
nanoparticles embedded into an AlxGa1−xAs semiconductor matrix. With an ab initio determined
dielectric function for bismuth and well-known dielectric properties of AlxGa1−xAs solid solution,
we performed calculations of the optical extinction spectra for such metamaterial using Mie’s theory.
The calculations demonstrate a strong band of the optical extinction using the localized surface
plasmons near a photon energy of 2.5 eV. For the semiconducting matrices with a high aluminum
content x > 0.7, the extinction by plasmonic nanoparticles plays the dominant role in the optical
properties of the medium near the resonance photon energy
