Abstract In our work, we investigate characteristics of conductivity for single-walled carbon nanotubes caused by spin–orbit interaction. In the case study of chirality indexes, we especially research on the three types of single-walled carbon nanotubes which are the zigzag, the chiral, and the armchair. The mathematical analysis employed for our works is the Green-Kubo Method. For the theoretical results of our work, we discover that the chirality of single-walled carbon nanotubes impacts the interaction leading to the spin polarization of conductivity. We acknowledge such asymmetry characteristics by calculating the longitudinal current–current correlation function difference between a positive and negative wave vector in which there is the typical chiral-dependent. We also find out that the temperature and the frequency of electrons affect the function producing the different characteristics of the conductivity. From particular simulations, we obtain that the correlation decrease when the temperature increase for a low frequency of electrons. For high frequency, the correlation is nonmonotonic temperature dependence. The results of the phenomena investigated from our study express different degrees of spin polarization in each chiral of single-walled carbon nanotube and significant effects on temperature-dependent charge transport according to carrier backscattering. By chiral-induced spin selectivity that produces different spin polarization, our work could be applied for intriguing optimization charge transport.

This work is an attempt to study the propagation of radial waves in an irregular single-walled carbon nanotube (ISWCNT). The characteristics equation of phase velocity of radial waves is derived using cylindrical thin shell theory. Taking into account the effects of the surface irregularity, dispersion curves are plotted and the effectiveness of surface irregularity is confirmed by comparing the obtained numerical results with those in cases of propagation of radial waves in uniform nanotube. The results turn out that, the phase velocity of radial waves is dependent on the surface irregularity and it is increasing with an increase of surface irregularity parameter. To the author best knowledge, propagation of radial waves in the irregular single-walled carbon nanotubes has not yet been studied, and the present work is an attempt to find out the dispersion relation of radial waves in ISWCNTs. Finally, the present results may serve as useful references for the application and the design of nano oscillators and nanodevices, in which single-walled carbon nanotubes act as the most prevalent nanocomposite structural element.
