摘要：

New dioxide nanotubes are described. These nanotubes are rolled up of a "square" lattice of atoms differing from the conventional hexagonal lattice isoelectronic to graphite. The dependence of the strain energy on the nanotube diameter D departs from a 1/D-2 behavior, and the optimum shape at the same diameter corresponds to "zigzag" tubelenes. Two-layer nanotubes consisting of an MO2 layer bonded to a carbon nanotube (CNT) are characterized by a considerably lower strain energy, which points to the possibility of using CNTs as a template for the synthesis of such MO2 nanotubes.
