dc.descriptionWe consider electronic structure and superconductivity aspects in field-doped polyacenes (PA) and C60. Within a modified Thomas-Fermi approach for typical experimental values of the surface charge density the injected charge is confined to a monolayer. The electron-phonon coupling constant for internal modes is estimated using the work of Devos et al. (Phys. Rev. B 58, 8236 (1998)) and the density of states N(0) estimated from a 2D-one-band model derived from a full potential LDA band structure calculation for bulk anthracene. The large differences in the reported Tc-values for n-doped PA and C60 are ascribed to enhanced empirical Coulomb pseudopotentials for polyacenes.
