    Theoretical study on electronic structures and spectroscopic regularities of ethylated single-walled carbon nanotubes

    The electronic structures of a series of ethylated single-walled carbon nanotubes (SWCNTs) were studied using density; function theory (DFT) at B3LYP/6-31G(d) level. The bond vertical to the main axis of the SWCN...
