In an exciton, the electron and hole are separated by the exciton radius. The attractive Coulomb interaction potential can induce quantization of energy. The exciton binding energy can be defined as the difference between the free electron energy and the quantized energy levels. 13 Schematic of exciton formation. With photon absorption, an electron is excited from the valence band to the conduction band. The electron can interact with the hole left in the conduction band by the Coulomb attractive interaction.

7eV/dt(nm). 7eV/dt(nm). 3 Effect of Curvature on Nanotube Bandgap Since SWCNT can be viewed as a rolled up graphene layer, in the zone-folding scheme, a periodic boundary condition is applied to the graphene layer in order to obtain electronic structures of the SWCNT. Actually, the SWCNTs have certain curvature due to the cylinder shape. Therefore, we cannot treat p orbitals independently as in the graphene case because the p orbitals are not orthogonal to s orbitals in the SWCNTs. The curvature of the SWCNTs mixes p and s orbitals, leading to certain deviations in the electronic structures of nanotubes 13 14 Fundamental Properties of Carbon Nanotubes from the pure p orbital graphene picture.
