A review of electronic band structure of graphene and carbon nanotubes using tight binding

The electronic band structure variations of single-walled carbon nanotubes (swcnts) using huckle/tight binding approximation theory are studied. according to the chirality indices,the related expressions for energy dispersion variations of these elements are derived and plotted for zigzag and chiral nanotubes. copyright © 2011 davood fathi.
