Thanks to an original approach based on the carburization of silicon nanowires, silicon carbide-based one dimensional nanostructures – SiC nanotubes, Si-SiC core-shell nanowires and SiC nanowires – have been synthesized. The original process, which relies on controlling the out-diffusion of Si atoms through SiC, can be monitored by the temperature, the pressure and the time of carburization. These SiC-based 1D nanostructures have been characterized by SEM, FIB-SEM and TEM microscopies and also Raman spectroscopy. Bio-nano-sensors, nano-Field-Effect-Transistors (nano-FETs) or gas sensors may be some applications for these nanostructures.
