Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0032] figure 1 It is a flow chart of a method for preparing an epitaxial wafer of a light-emitting diode provided by an embodiment of the present invention, such as figure 1 Said, the preparation method comprises:
[0033] S101: Provide a substrate.
[0034] S102: growing a buffer layer on the substrate.
[0035] S103: forming a cylindrical N-type GaN layer on the buffer layer, the axis of the N-type GaN layer being perpendicular to the surface of the substrate where the buffer layer is grown.
[0036] S104: forming a cylindrical P-type GaN layer on the buffer layer, the P-type GaN layer is coaxially sleeved outside the N-type GaN layer, and an annular light-emitting gap is formed between the P-type GaN layer and the N-type GaN lay...
