Title: Methods involving spin-on polymers that reversibly bind charge carriers

Abstract: Methods for improving memory retention properties of a polymer memory cell are disclosed. The methods include forming a first electrode, depositing a passive layer over the first electrode, forming a semiconducting polymer layer containing at least one semiconducting polymer with at least one charge carrier-binding group over the passive layer, and forming a second electrode. The charge carrier-binding groups can be incorporated into semiconducting polymers either as side groups or into the main chain of semiconducting polymers.
