Electronic properties of gold nanotubes (5, 3) and (5, 0) in the Hubbard model in the static fluctuation approximation

Abstract

A theoretical analysis of the electronic properties of single-walled gold nanotubes with chiralities (5, 3) and (5, 0) with the growth of nanotubes is presented. The results of the study of single-walled gold nanotubes with chiralities (5, 3) and (5, 0) were compared with the results obtained by X.P. Yang and J.M. Dong. The Hubbard model with a certain selection of model parameters allows us to explain the data obtained using the electron density functional theory. According to our results, only the semiconductor–metal transition occurs with the growth of gold nanotubes, and there are no semiconductor–metal–semiconductor–metal “oscillations”, which were indicated in the following work: X.P. Yang and J.M. Dong, Phys. Rev. B 71, 233403 (2005).
