Firstly, the research background and significance of nanostructures and their materials are introduced, and then the current preparation methods and their advantages and disadvantages of nanowires are analyzed. Then, the principle and process of making nanowires by MOVPE method are described in detail, and the experimental conditions are optimized according to the research purpose. Finally, the structure and properties of the prepared nanowires were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD), Raman spectrometer, etc. The results showed that the prepared ZnSeGe heterostructure nanowires had excellent electronic and optical properties, and were suitable for applications in electronic devices and optoelectronic devices.Keywords: nanowire, heterostructure, metal organic vapor phase epitaxy (MOVPE), characterization
