Charge transport and spin physics of high mobility organic semiconductors

Prof. Henning Sirringhaus, University of Cambridge

Over recent years several new classes of conjugated polymer and small molecule organic semiconductors have shown promise as materials for organic field-effect transistors. Many of these recently discovered high mobility conjugated polymers, in particular donor-acceptor copolymers, are characterised by a puzzling lack of pronounced crystalline order, while the best molecular semiconductors are highly crystalline but exhibit strong electron-phonon coupling. In this presentation I will present our current understanding of the charge transport and spin physics of these materials and of the reasons why these van-der-Waals bonded materials can exhibit such high carrier mobilities. I will also give an introduction to some of the applications in large-area flexible sensors and active-matrix addressing of flexible liquid crystal and OLED displays.
