Inkjet-printed silver nanoparticle electrodes on GaN-based micro-structured light-emitting diodes

Silver nanoparticle ink has been inkjet printed onto inorganic GaN-based micro-structured light-emitting diodes to form narrow conductive tracks with a width down to ~30 mum and a resistivity value approximating that of a conventional sputtered metal (Ti/Au) track. These silver tracks serve as `active' electrodes with comparable performance to the deposited metal tracks, demonstrating a new, simple and cost-effective route for the electrode fabrication of GaN-based LED devices.
