摘要
A quantum-chemical model of multiwalled nanotubes of magnesium diboride was produced. The electronic structure and the nature of the interatomic bonds in the multiwalled nanotubes were studied in relation to the diameter and the number of Mg-B2 layers: (6,6) → (3,3)@(6,6) → (6,6)@(12,12) → (3,3)@(6,6)@(12,12). Possible methods for the production of diboride nanotubes are discussed. Features of the electronic states in composite nanotubular structures based on the diborides of s and p metals are examined for the first time as illustrated by the (6,6)AlB2(12,12)MgB2 multiwalled nanotube.
