Charge transport at conjugated polymer-inorganic semiconductor and conjugated polymer-metal interfaces.
Charge transport at conjugated polymer interfaces with metals and inorganic semiconductors is reviewed. Experiments on the equilibrium properties and DC current-voltage behavior of four specific classes of interfaces-metal-doped conjugated polymer, inorganic semiconductor-doped conjugated polymer, metal-intrinsic conjugated polymer, and metal-intrinsic conjugated polymer/electrolyte-are discussed. To facilitate this discussion, classic models of equilibration at ideal interfaces between electronic conductors and free-electron transport are introduced and their limitations discussed. Particular emphasis is placed on the charge distributions and interfacial potential profiles expected at various types of electroactive interfaces.
