Electronic structure of hybrid interfaces for polymer-based electronics — •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 molecular modification of energy level alignment at hybrid interfaces have been carried out for many years. Molecular adsorption may be used to control interfacial electronic parameters almost as-desired for applications in molecular and polymer based electronic applications. 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. Several examples of recent work on the molecular modification of hybrid interfaces, carried out in Linköping, will be presented. In addition, some very recent results on fast charge transfer at hybrid interfaces, studied by variations on UPS, will be discussed.
