Band structure variation for SWCNTs under deformation

Abstract EN

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.
