Abstract

The plasmonic response from a nanotextured silver coating was utilized to enhance the transfer of ultraviolet light generated in a group-III nitride nanowire emitter. A two-step approach was developed in a metal-organic chemical vapour deposition system to grow nanowires initially vertically by the vapour-liquid-solid mechanism and, subsequently, laterally by increasing the growth temperature and the group-V/III reactant ratio. This controllably produced a 20 nm GaN:Si core with a 200 nm outer-diameter AlGaN:Mg sheath structure. Solvothermal chemistry based on an ethylene glycol solvent was employed to deposit a silver coating that approximated a dense packing of metallic nanospheres. Nanoscale emission and plasmonically enhanced transfer of this energy were simulated to aid the development and understanding of this system.
