Webinfrared spectroscopy (FTIR). The results show that the as-synthesized nanowires are high-quality crystals with high aspect ratios. Moreover, high density of SiC nanowires have been successfully grown even at a low temperature of 900℃. Additionally, it has been observed that the phonon states of SiC nanowires are different from the bulk SiC.
