Organic Materials for Electronics: Proceedings of Symposium D of the 1994 E-Mrs Spring Conference, Strasbourg, France, 24-27 May 1994(Vol 49 European Materials Research Society Series)

The proceedings of this interdisciplinary symposium focus mainly on surfaces and interfaces of conjugated polymers. Aspects of both the basic materials science of conjugated polymers as well as present development technology of proto-typical devices based on these polymers are discussed. Much attention is paid to the new light-emitting diodes (LEDs) based on conjugated polymers. The proceedings begin with overviews of the experimental and theoretical methods used in the studies of (conjugated) polymer surfaces and interfaces. New developments in conjugated polymer-based LEDs in the USA are then presented and not only the device issues but also the basic physics studied in connection with, and with the help of, the LED device structures are dealt with. Other topics of importance included in these proceedings are metal/polymer interfaces, STM/AFM of organic molecular systems, the processing of ultrathin films of ordered PTFE, characteristics of LEDs and polymeric opto-chips. The main issues which evolved during the course of the symposium are represented by the new polymer-based LEDs and use of conjugated polymers in opto-electronics applications.
