摘要：

We report the results obtained from electrical measurements and surface analysis by photoelectron spectroscopy (XPS) performed in polyparaphenylene-vinylene (PPV) thin films sandwiched between metallic electrodes. Current-voltage characteristics of metal-polymer-metal devices are dissymetrical with rectifying contacts at top electrodes (Cr or Al) and blocking one at bottom electrodes (Cr). Analysis of the core level spectra of carbon, oxygen and metals in the interfacial layers leads to the conclusion that the rectifying behaviour of polymer-metal contact is in close relation with the formation of metallic oxide-carbon complexes at the interfaces.
