Aspects of the superconductivity in doped polyacenes — •S.-L. Drechsler1, H. Rosner2, and S.V. Shulga 1 — 1Institut für Festkörper- und Werkstofforschung Dresden, P.O. Box 270116, D-01171 Dresden, Germany — 2Department of Physics, University of California, Davis, CA-9561, USA
Several theoretical aspects of the recently discovered superconductivity [1] in field doped polyacenes are considered. The electron-phonon coupling constant for internal modes λintra is estimated using the results of Ref. 2 and the density of states N(0) estimated from a full potential LDA band structure calculation for anthracene within the rigid band approximation. The strength of the el−el interaction as well as the effect of the strong electric field are briefly discussed.
