Excitonic polaron in the photoemission spectra of C60 and the origin of high-Tc superconductivity of doped fullerenes
Alexandrov A. S. , Kabanov V. V.
The photoemission spectrum of C^q is well-described over a wide energy region by the small polaron theory with polaron-exciton coupling. The strongest coupling is found for the Ag2 pinch mode and an —0.5 eV Frenkel exciton. © 1995 American Institute of Physics.
