摘要：
The authors have demonstrated nitride-based near-ultraviolet (NUV) light emitting diodes (LEDs) with mesh indium tin oxide (ITO) contact layer. With 20 mA injection current, it was found that forward voltages were 3.94 and 4.05 V while the output powers were 7.54 and 9.02 mW for the planar ITO LED and mesh ITO LED, respectively. The larger LED output power should be attributed partially to the reduced absorption of ITO in the NUV region and partially to the better current spreading. (c) 2006 American Institute of Physics.
