Abstract:
1. A method for improving at least one of carrier ion/charge mobility, permeability and distribution in a semiconducting polymer layer of a polymer memory cell, comprising: providing a first electrode on a substrate; forming a passive layer over the first electrode; forming a semiconducting polymer layer over the passive layer, wherein the semiconducting polymer layer comprises at least one semiconducting polymer comprising one or more ion-complexing side-chain groups that reversibly binds, complexes, or accepts carrier ions/charges, the proportion of ion-complexing side-chain groups to a monomeric precursor of the semiconducting polymer ranges from about 0.01:1 to about 1:1 to facilitate carrier ion/charge mobility by providing a path for carrier ion/charge motion from one ion-complexing side-chain group to another; and providing a second electrode over the semiconducting polymer layer.
