There have been a large amount of studies concerning the fabrication and properties of silicon carbide nanowires. In fact, much more knowledge has been learnt about SiC nanowires than other low-dimensional SiC nanostructures. A lot of methods have been developed to synthesize SiC nanowires and some can yield large-scale and high-quality SiC nanowires and nanowire arrays. Filed electron emission is the most intensively investigated characteristic of SiC nanowires and there are also some studies involving the luminescence properties of SiC nanowires. SiC nanorods, nanobelts, and various other forms of one-dimensional nanostructures have also been synthesized and studied.
