The electronic properties of carbon nanotubes CNTs, such as ionization potential (IP), electron affinity (EA), energy gap (Eg), Fermi energy (Ef), binding energy (Eb), the density of state (DOS), and IR spectral properties, investigated after substituted the OH, SO, SiO2, H2O, and N2 groups on the optimization structure of CNT (3,3). The lengths of C=C for zigzag CNT (3,3) slight altered with substituted the mention groups and given the depress in bond length during the substituted –OH, -SO, and –SiO2 that attitude to bond orders for these substituted groups and different in electronegativity power for an oxygen atom in these groups. Moreover, the C-C bond for zigzag CNT (3,3) changed also, and gave a slight increase during the substituted OH group, but decreased during substituted So and SiO2 groups. The substituted of –SO and –SiO2 on the structure of CNT (3,3) demonstrated, fewer values of total energies that will increase the stability of CNT. The CNTS-SiO2 has a less value for bandgap compared with other substituted materials, this behaver has given it a good electronic conductivity. The B3LYP functional theory has been used to conduct the DFT approach. The analyzed Nano species agree well with the experimental results based on the measured values of HOMO and LUMO energies. The Gaussian 09 program was used to calculate all feature values.
