초록
We have demonstrated that the light extraction efficiency of GaN based light emitting diodes (LEDs) can be significantly enhanced by using photonic crystal and microcavity (PCMC) effects. It was found that the extraction efficiency of the PCMC-LEDs is 9.5 times larger than that of the normal LEDs.
