Mechanical properties of SiC nanotubes

Keywords: SiC, nanotube, mechanical property

Abstract:
We investigate the mechanical properties of SiC nanotubes using molecular dynamics simulation. We find that SiC nanotubes are less stiff than the other nanotubes considered so far, such as BN or C nanotubes. However, Young's modulus for SiC nanotubes is larger than that of β-SiC and almost equal to the experimental value for SiC nanorod and SiC whisker. The strain energy of the SiC nanotubes of a given diameter, is lower than that of the other nanotubes. In spite of the large energy cost between SiC nanotube and β-SiC, our calculations suggest the possibility for the synthesis of SiC nanotubes.
