Abstract
The indium-tin oxide (ITO) films with low sheet resistance and conduct ing transparency have been used on the AlGaInP double-heterostructure orange light-emitting diodes (LED's) to improve the light extraction f rom the LED surface and device reliability, The orange LED's with ITO films exhibit a light output power of 1 mW at 50 mA, which is correspo nding to an external quantum efficiency of 1.1%, They can operate stab ly for more than 3000 h at 20 mA and 25 degrees C without any degradat ion.
