Title: | Electron-phonon interaction in cylindrical nanostructures | Authors: | Šajfert, Vjekoslav Mašković, Ljiljana Jaćimovski, Stevo Popov, Dušan Tošić, Bratislav |
Issue Date: | 1-Jan-2008 | Journal: | Journal of Computational and Theoretical Nanoscience | Abstract: | The superconductivity properties of cylinder with nano cross-section are investigated. In the nearest neighbours approximation, electron Hamiltonian of cylinder decays onto two independent Hamiltonians. One corresponds to electrons which propagate along chains parallel to the axis of cylinder. Second correspond to electrons moving in discs. The electron-phonon interaction Hamiltonians are found and superconductive properties were examined in the frames of BCS approach. It was shown that superconductive temperature in chains is several Kelvins, while in discs it can be higher for two orders of magnitude. It is also shown that magnetic field produced by electron currents in discs is of the order of thousand Tesla, i.e., extremely high. Copyright © 2008 American Scientific Publishers.
