"Electronic Structure of Hybrid Interfaces"
Dr. William R. Salaneck
Department of Physics, IFM, Linköpings Universitet, S-581 83 Linköping, Sweden
Conjugated polymers are currently used in organic molecular and polymer based electronics. The interface between the organic material (molecular or polymeric) and inorganic electrode materials controls a great deal of the interfacial charge transfer characteristics. In Linköping, studies of energy level alignment (and molecular modification thereof) at hybrid interfaces have been carried out for many years. The characterization of the electronic structure of the interface between spin-coated polymer films and metallic substrates (the device fabrication mode), is often carried out using photoelectron spectroscopies. Recent work on charge transfer at hybrid interfaces, and also at subsequent organic-organic interfaces, carried out in Linköping, will be presented. In addition, some rather preliminary results on the use of self-assembled monolayers (SAM’s) at hybrid interfaces will be included as a topic for discussion.
