ABSTRACT:
Improving memory retention properties of a polymer memory cell are disclosed. The methods include providing a semiconducting polymer layer containing at least one organic semiconductor and at least one of a carrier ion oxidation preventer and an electrode oxidation preventer. The oxidation preventers may contain at least one of 1) an oxygen scavenger, 2) a polymer with oxidizable side-chain groups which can be preferentially oxidized over the carrier ions/electrodes, and 3) an oxidizable molecule that can be preferentially oxidized over the carrier ions/electrodes.
