Simulation of Plasmon Enhanced Radiation from SiGe Quantum Dots Combined with Silver Nanoparticles

Abstract

This paper describes a theoretical study of the effect of amplification of radiation from quantum dots upon resonance excitation of localized surface plasmons in three-dimensional silver nanoislands located on the surface of a Ge/Si heterostructure with quantum dots. It was found that the interaction of the emitters with silver nanoparticles can lead to a significant increase (by more than an order of magnitude) in the yield of radiation from the hybrid structure.
