This investigation presents nitride-based near ultraviolet (n-UV) light emitting diodes (LEDs) with a meshed p-GaN layer. With 20 mA injection current, it was found that forward voltages were 3.29, 3.31 and 3.39 V while output powers were 7.5, 9.0 and 10.6 mW for the planar indium-tin-oxide (ITO) LED, mesh ITO LED and meshed p-GaN LED, respectively. The larger LED output power is attributed to increased light extraction efficiency. It was also found that we could use such a meshed p-GaN layer to achieve reliable nitride-based n-UV LEDs.
