CONTACT PROPERTIES OF METAL/POLYACETYLENE INTERFACES.

Abstract

There is presently a rapidly growing research in the organic polymeric materials areas. The interest devoted to these semiconductors is essentially justified by the low cost and easy fabrication of thin films needed for such applications as thin film transistors, solar cells or opto-electronic devices. However, the stability of polymeric materials, even being improved during the past years, are still the open question. Recognizing the material limitations and the fact that the polymeric devices are very far from the ideal textbook case, the physics and chemistry of these systems are a very attractive subject to investigate. Furthermore, the absence of any detailed study of these devices had increased motivation to investigate the contact properties of metal/polyacetylene interfaces. The results of this study will be presented.
