Question

describe the electronic structure of carboon nanotube

Answer 1

The electronic structure of each C atom is 1s²2s²2p_x¹2p_y¹2p_z^0_.Carbon atoms in graphite are sp² hybrized. In graphite the carbon atoms are hexagonally arranged to form layers. Each such layer is known as graphene. In graphite the layers are arranged at a distance of 0.34 nm between two layers. Fullerenes contain large cage like structures of about 60 or more carbon atoms.Carbon nanotubes have cylindrical structures containing graphite sheets with hemispherical fullerenes or a graphite sheet at the ends.The electronic properties of carbon nanotubes depend on the wedge angle of the graphite sheets.
