Ultrafine ZnO nanorods can be directly grown on carbon-coated SiC nanowires using metalorganic chemical vapor deposition at temperatures of 500~600℃. First, carbon-coated SiC nanowires were fabricated on NiO catalyzed Si(100) in a WO3 and C carbothermal reduction environment. The diameter range of SiC nanowires was 20~50nm. We flowed DEZn source for 1~2 hours on the SiC nanowires, then ZnO nanorods were grown on the surface of SiC nanowires without the presence of a catalyst. The diameter range of ZnO nanorods was 7~20nm. Heterostructures were analyzed by SEM, EDS, TEM, XRD. |
