Study of physical properties of single walled SiC nanotube (8,8) in crystalline bundles by DFT

► Study of the physical properties of SiC sheet and isolated and bundled NT-SiC. ► Effects of inter-tube interaction on band splitting, band gap, DOS and Fermi energy. ► Increase of the bulk modulus for the bundled NT compared with the isolated form. ► Increase of probability of being made into bundled NT in comparison with other cases.
