Abstract
We applied graphene network on Au nanoclusters as a transparent and current spreading electrode in GaN-based ultraviolet (UV) light emitting diode (LED). The electroluminescence (EL) of UV-LEDs with graphene film on Au nanoclusters was enhanced by 10% at injection current of 20 mA, while keeping reasonably good injected current-voltage (I-V) characteristics. This result is attributed to the reduction of absorption at UV wavelength region, effective current spreading and injection by reduced sheet and contact resistance, and texturing effect through Au nanocluster.
