Exciton radiative decay through plasmon modes in planar metal-semiconductor structures
arXiv:1209.3372 · doi:10.1103/PhysRevB.87.195429
Abstract
We develop a non-local dielectric response theory to describe the temperature dependence of exciton lifetime in metal-semiconductor heterostructures. Coupling between excitons and surface plasmons results in a strongly nonmonotonous behaviour of exciton radiative decay rate versus temperature. Tuning the plasmon frequency one can control the efficiency of exciton emission of light.
