The method is characterized by firstly subjecting the Si substrate to an annealing treatment to obtain a clean reconstituted Si surface, then preparing the island-shaped AlN nucleating points by developing and optimizing the growth method and technology of a nucleating layer of AlN, and regulating the distribution and morphology of the nucleating points by optimizing the annealing temperature and nitridation time, and finally, preparing the GaN nanowire on the optimized island-shaped AlN nucleating points. During growth, V/III is set by fixing a metal source beam current and a higher N 2  plasma flow rate; and real-time in situ monitoring is performed on the nucleation process by using a reflected high-energy electron diffraction pattern. In addition, a GaN nanowire with a higher quality and a hexagonal morphology is prepared by optimizing the temperature of the substrate.
