Peierls transition with acoustic phonons and twist deformation in carbon nanotubes

Abstract

We consider the Peierls instability due to the interaction of electrons with both acoustic and optical phonons. We suggest that such a transition takes place in carbon nanotubes with small radius. The topological excitations and the temperature dependence of the conductivity resulting from the electron-lattice interactions are considered.Comment: 5 pages, 3 PostScript figures included; submitted to Phys.
