An electron energy-loss study of picene based charge transfer salts — •Eric Müller, Benjamin Mahns, and Martin Knupfer — IFW-Dresden, P.O.Box 270116, DE-01171 Dresden, Germany

The electronic excitations of coevaporated thin films of TCNQ/picene and F4TCNQ/picene have been investigated using electron energy-loss spectroscopy. We demonstrate that the investigated molecular pairs support charge transfer which result in new electronic excitation features at low energy. We discuss the character and localization of these low energy excitations. This work was supported by the DFG (KN393/14).
