Abstract
A light emitting diode (or) includes a diode structure containing a quantum well (), an enhancement layer (), and a barrier layer (or) between the enhancement layer () and the quantum well (). The enhancement layer () supports plasmon oscillations at a frequency that couples to photons produced by combination of electrons and holes in the quantum well (). The barrier layer serves to block diffusion between the enhancement layer () and the diode structure.
