Synthesis and Property of One-Dimensional Metal/Semiconductor Heterojunction Nanomaterials

One-dimensional metal/semiconductor heterojunction nanomaterials have been tremendously concerned because of their novel structures, unique electrical and optical proper-ties, and central roles in fabricating electronic nanodevices. In this paper, the recent progress in synthesis and property study of metal/semiconductor heterojunction nanomaterials has been systematically reviewed based on the latest literatures and our works. Some important synthetic methods such as chemical vapor deposition method, thermal evaporation deposition method, template method, self-assembly method, and solution-phase method are introduced, and their advantages and disadvantages of the heterojunction nanomaterials are analyzed. The properties of the metal/semiconductor nanomaterials such as Coulomb blockade effect, Schottky diode behaviour, Ohmic contact property, and eletroluminescence property are analyzed in detail. It is pointed out that solution-phase method to effectively prepare the high-quality metal/semiconductor nanaomaterials is indicated as the dominant orientation of future development on the preparation and property study of the heterojunction nanomaterials.
