Field-induced carrier generation in conjugated polymer semiconductors for dynamic, asymmetric junctions
A functioning dynamic memory device has been created using a polypyrrole composite material that contains immobilized anions and highly mobile cations in the form of a thin film spanning two metal electrodes in an interdigitated electrode array configuration. Dynamic asymmetric electronic behavior based on the movement of charge in response to the application of a field is demonstrated. The material system described has significant advantages for application in nanometer-scale electronics.
