| 英文摘要 | An (Al,In,Ga)N and ZnO direct wafer bonded light emitting diode (LED), combined with a second light extractor acting as an additional light extraction method. This second light extraction method aims at extracting the light which has not been extracted by the ZnO structure, and more specifically the light which is trapped in the (Al,In,Ga)N layer. This second method is suited for light extraction from thin films, using surface patterning or texturing, or a photonic crystal acting as a diffraction grating. The combination of both the ZnO structure and the second light extraction method enables most of the emitted light from the LED to be extracted. In a more general extension of the present invention, the ZnO structure can be replaced by another material in order to achieve additional light extraction. In another extension, the (Al,In,Ga)N layer can be replaced by structures comprising other materials compositions, in order to achieve additional light extraction. |
