| Abstract | ||
| The electronic properties of single walled carbon nanotubes (SWCNTs) influenced by the mechanical elastic deformation are investigated by using a tightbinding approximation. We analyze the band structure for SWCNTs in a wide range of energies around a Fermi energy level. Our work includes the uniaxial, torsional and sublattice deformation, which is applied to modify the electronic transport properties of SWCNTs, e.g. the energy spectrum as a function of the deformation tensor. However, the results showed that the electronic properties of SWCNTs are affected by deformation processes, where the energy spectrum is changed perceptibly. | ||
