Evidence of intrinsic ambipolar charge transport in a high band gap organic semiconductor

By César Moreno, Raphael Pfattner, Marta Mas-Torrent, Joaquim Puigdollers, Stefan T. Bromley, Concepció Rovira, Jaume Veciana and Ramón Alcubilla, London (2011)

Theoretical and experimental investigations combining in situ Kelvin probe microscopy (KPM) and macroscopic electrical studies are employed to explore the intrinsic transport in dithiophene-tetrathiafulvalene (DT-TTF) single crystal organic field-effect transistors. Our work demonstrates that ambipolar behavior is not restricted only to materials possessing a high electron affinity and thus may be a more general phenomenon.
