Abstract
We underline the intrinsic rectifying nature of an oriented polymeric material. Orientation of the initially symmetric structure is performed through DC-field ordering of the polar molecules contained in the polymer. The internal field induced in the polymeric material is evidenced by the induction of a rectifying current-voltage characteristic. Our preparation technique opens a new route for the improvement of organic-semiconductor devices efficiency.

Résumé
Nous soulignons la nature intrinsèquement rectifiante d'un polymère orienté. L'orientation moléculaire est induite par polarisation sous champ permanent. Le champ interne piégé dans le matériau induit une rectification de la caractéristique courant tension. Notre technique de préparation ouvre une voie nouvelle pour l'amélioration des performances des dispositifs semiconducteurs organiques.
