SiC nanorods were synthesized by a reaction at a temperature of 1200°C, under an argon gas atmosphere, from silicon and amorphous carbon powder mixed by ball milling. The reaction products, which contain SiC nanorods, were characterized by X-ray diffraction and micro-Raman spectroscopy. The synthesized nanorods are more than 1 micron long with a mean diameter of about 10-30 nm. The nanorods possess a well-defined crystaline structure with a thin layer of amorphous SiO2 on the surface. Raman shifts of SiC nanorods and the role of structural defects are discussed.

Abstract
SiC nanorods were synthesized by a reaction at a temperature of 1200°C, under an argon gas atmosphere, from silicon and amorphous carbon powder mixed by ball milling. The reaction products, which contain SiC nanorods, were characterized by X-ray diffraction and micro-Raman spectroscopy. The synthesized nanorods are more than 1 micron long with a mean diameter of about 10-30 nm. The nanorods possess a well-defined crystaline structure with a thin layer of amorphous SiO2 on the surface. Raman shifts of SiC nanorods and the role of structural defects are discussed.File in questo prodotto:
