Use of a charge storage layer composed of a polymer insulator of PMMA and a soluble small-molecule semiconductor of TIPS-pentacene in top-gate organic field-effect transistors (OFETs) based on polymer semiconductors enables the solution processing of nonvolatile memories. Here, we fabricate top-gate n-channel OFET memory devices using a high electron mobility donor-accepter polymer semiconductor of PNDI(2OD)2T by spin-coating processes and investigate their memory characteristics. We found that PNDI(2OD)2T FET memories do not exhibit memory operations in the dark, while threshold voltage shifts are observed by programming under light illumination. It is also observed thar the addition of soluble fullerene molecules of PCBM to the charge storage layer allows improving erasing characteristics. |
