About interaction boron-carbon nanotubes with metal atoms

Abstract

We assumed that in our earlier papers that the interaction between some metal atoms and their intercalation inside the nanotube is possible. These facts suggest us that the boron-carbon nanotube may be the new material, which is as well as pure carbon nanotube become the basis of the nanoelelctronic devices. For this reason the continuation of metal adsorption mechanism studying is important. The way of intercalation (doping) of alkaline metal inside the BC3-nanotube and modeling of the regular external adsorption is suggested. Results of researches showed that doping of boron-carbon nanotubes is possible and the electron density is distributed near nanotube surface atoms. Regular external adsorption of the alkaline metal atoms causes decreasing of the energy gap compared with the pure boron-carbon nanotube. So, we can obtain that intercalation of metal atom inside the BC
