Interaction of Na with sexithiophene thin films [link]Paper  doi  abstract   bibtex   
The effects of Na on the electronic structure and electrical properties of α-sexithiophene (α6T) are investigated with electron spectroscopic methods under UHV conditions. A shift of the valence-band edge away from the Fermi level, and the evolution of states in the gap, can be determined. In a classical band-structure picture this could be explained as an n-type doping process. However, all results point at a high localization of the negative charge at the sulfur atom which is reflected in a very low specific conductivity.
