(Color online) Schematic of SOI LED used in the experiments.
(a) AFM image showing elevation of the metal particles. (b) SEM picture of the silver islands on the SOI LED.
(Color online) Shift in the bare island resonance using dielectric overcoating.
(Color online) (a) EL plots before and after the deposition of silver islands and overcoating. (b) Enhancement plots for the data from (a) also showing the variation of the reference sample without the silver islands (dotted line).
EL image showing the difference in EL from one LED that is partially covered with silver islands (left). Brighter areas correspond to higher EL intensity.
(Color online) Photocurrent enhancement plots for the case with metal islands and for the case of metal islands overcoated with .
