Exciton radiative decay through plasmon modes in planar
metal-semiconductor structures [PDF]
M. V. Durnev, A. V. Kavokin, B. GilWe 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.View original: http://arxiv.org/abs/1209.3372
