Research DESCRIPTION

One-dimensional (1D) nanostructures have been drawing significant attention because of their novel electrical, mechanical and optical properties. These include nanowires, nanotubes, nanorods and nanofibers with appreciably high aspect ratio. Silicon carbide (SiC), a wide-gap semiconductor is a promising candidate in this field owing to its excellent physical and electrical properties. Being biocompatible and chemically inert, silicon carbide offers widespread application in nanoelectronics, nanosensors, optoelectronics and biomedical field as well.  The objectives of our work include synthesis of 1D SiC nanostructures by chemical vapor deposition(CVD), characterization of the synthesized nanostructures, study of variation in properties with doping and applications of the 1D SiC nanostrutures in sensing and solar cell technologies.
