Electrically rewritable memory cells from poly(3-hexylthiophene) Schottky diodes

Rewritable plastic memory cells are made from polythiophene doped with inorganic salts and a plasticizer. The memory can be written and erased at +/- 6 V (see Figure) and read out is non-destructive. The retention time at zero bias is on the order of several minutes.
