Stability and electronic properties of hybrid coaxial carbon nanotubes–boron nitride nanotubes under the influence of electric field

We investigated the electronic properties of coaxial carbon nanotube–boron nitride nanotube hybrid system under the influence of external electric field. Although the clear discrepancy in the electronic properties between the configurations used in this study, we found that the electronic properties of both hybrid configurations show almost the same as the electronic states near the band edges of carbon nanotube. We also found that the interaction force between the outer boron nitride nanotube and inner carbon nanotube is repulsive force, whereas the interaction force between the outer carbon nanotube and inner boron nitride nanotube is attractive force. Furthermore, applying external electric field gradually modifies the band gap and a semiconductor–metal transition achieved. In addition, the redistributed charges are more localized in the certain atoms in outer carbon nanotube and inner boron nitride nanotube coaxial structure. Moreover, different combinations between carbon nanotube and boron nitride nanotube might lead to new materials with tunable electronic properties. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature.
