Exciton binding energies in organic semiconductors
TL;DR: In this article, it was shown that the previously reported values for the exciton binding energy in many organic semiconductors, which differ by more than an order of magnitude, can be consistently rationalized within the framework of the charging energy of the molecular units, with a simple dependence of the binding energy on the length of these units.

Electronic properties of carbon nanostructures
TL;DR: A review of experimental studies of the electronic structure of carbon nanostructures using high-energy spectroscopies such as photoemission and electron energy-loss spectroscopy is presented and discussed in this paper.

Mark S. Golden,Martin Knupfer,J. Fink,J.F. Armbruster,T.R. Cummins,H. Romberg,M. Roth,M. Sing,M. Schmidt,E. Sohmen +9 more
TL;DR: In this article, the high-energy spectroscopic study of the electronic structure of fullerenes and their compounds in the solid state is reviewed, and the role played by electron correlation, disorder and electron-phonon coupling is discussed.
Journal ArticleDOI
Studies of fullerenes by the excitation, emission, and scattering of electrons
TL;DR: In this article, an overview of how electron spectroscopies have contributed to advances in fullerene research is presented, which illustrates the vital role these techniques have played in improving our understanding of the importance of strong electronic correlation and of electron-phonon coupling in these materials, in the derivation of electron hopping rates, in providing a direct determination of charge transfer and hybridisation in both ful lerene salts and adsorbed fullerenes and in determining the optical gap of these systems.

Absence of photoemission from the Fermi level in potassium intercalated picene and coronene films: structure, polaron or correlation physics?
TL;DR: None of the films studied shows emission from the Fermi level, i.e., the authors find no indication for a metallic ground state, and several reasons for this observation are discussed.
