Embodiment Construction
[0026] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.
[0027] figure 1 It is a schematic structural diagram of an epitaxial wafer of a light emitting diode provided by an embodiment of the present disclosure. Such as figure 1 As shown, the epitaxial wafer includes a substrate 10 and an AlN buffer layer 20, a three-dimensional nucleation layer 30, a u-type GaN layer 40, an n-type GaN layer 50, a multi-quantum well layer 60, and a low-temperature p type layer 70, electron blocking layer 80 and high temperature p-type layer 90.
[0028] Wherein, the multi-quantum well layer 60 includes a plurality of In x Ga 1-x N quantum well layer 61 and a plurality of GaN quantum barrier layers 62, and the In x Ga 1-x A composite structure 63 between the N quantum well layer 61 and the GaN quantu...
