What is Study of Orientation Induced Molecular Rectification in Polymer Films about?

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. Second harmonic generation is used as a probe of the molecular order. Orientation induced rectification is proportional to the molecular order. This preparation technique opens a new route for the improvement of organic-semiconductor devices efficiency. Additionally, electric-field induced second-harmonic generation (EFISHG) is used as an internal field measurement technique. It offers an original characterization tool for charge injection and transport studies in organic semiconductors.
