We report an eight-fold enhancement in electroluminescence from silicon-on-insulator light-emitting diodes at 900nm via excitation of surface plasmon resonance in silvernanoparticles, along with a redshift in the electroluminescence by 70nm by overcoating the nanoparticles with ZnS. The enhancement is due to coupling between the electromagnetic excitations of the silvernanoparticles and the waveguide modes.The Centre of Excellence for Advanced Silicon Photovoltaics and Photonics is supported under the Australian Research Council’s Centres of Excellence Scheme.© 2006 American Institute of Physics.Keywords: Electroluminescence; Electromagnetic field effects; Light emission; Nanostructured materials; Semiconductor lasers; Surface plasmon resonance; Zinc sulfide; Electromagnetic excitations; Si devices; Waveguide modes; Light emitting diodes2006-04-1710.1063/1.21956952015-12-09
