Abstract

Theoretical analysis of the electronic properties of single-walled gold nanotubes of chiralities (5, 3) and (5, 0) with the growth of nanotubes is given in comparison. The results of the study of single-walled gold nanotubes (5,3) and (5, 0) were compared with the work of Yang X.P. and Dong J.M. (2005). The Hubbard model we used with a certain choice of model parameters allows us to explain the data obtained using the electron density functional theory, but according to our results, with the growth of gold nanotubes, only the semiconductor–metal transition without semiconductor–metal–semiconductor–metal oscillations takes place as it follows from the work of X.P. Yang and J.M. Dong (2005).

Key words: Hubbard model, single-walled gold nanotubes (SWGT), Green function, electron density of states, forbidden zone, nanosystem, nanoparticle.
