Hot-Wall Epitaxial Growth of Films of Conjugated Molecules

Research on conjugated organic systems is a rapidly expanding field at the turn of chemistry, condensed matter physics, materials science, and device physics due to the promising opportunities for applications of these π-electron semiconductors in electronics and photonics. Due to their interdisciplinarity, this class of materials attracted the attention of a large number of researchers and triggered the beginning of a “revolution” in organic electronics. Originating with an initial focus on the p- and n-doping of conjugated oligomers and polymers, the unique electrochemical behavior of these technological important materials enabled the development of cheap sensors. Because of the progress toward better developed materials with higher order and purity, these organic materials are now also available for organic electronic devices. More generally, organic electronics includes now diodes, photodiodes, photovoltaic cells, light-emitting diodes, lasers, field-effect transistors, electrooptical couplers, and all organic integrated circuits, and claims thereupon for key technology of the twenty-first century [1].
