| Abstract: | Superconducting vibronic interaction has been examined for a model of Si-substituted polyacetylene. Large attractive vibronic interaction for the formation of superconducting electron pair has been found for the electron scattering process in between the  and in-plane  orbitals in silene unit. Doping of holes in these orbitals would be done by extracting electrons from the out-of-plane orbitals as well as from the in-plane orbitals. If stacking of the model polymers is performed in a parallel manner, the interplane electron pairing has also been found to be favorable on account of small Coulombic repulsion. |
