| Abstract: | Photonic crystals (PCs) have attracted much attention during the last decade as a solution to overcome the low extraction efficiency of as-grown light-emitting diodes (LEDs). In this review,the underlying physics mechanism for enhancing the extraction efficiency of GaN-based LEDs by using the PCs structure is described. Based on analyzing the parameters of different structures,lattice constants and highness of various PCs,several novel PC LEDs are introduced and progresses obtained in these decades are pres... |
