Polymeric charge storage electrets for non-volatile organic field effect transistor memory devices

In this review, we present the effects of the chemical structure and composition of polymer or composite electrets on tuning the memory characteristics of the non-volatile organic field effect transistor (OFET) memory devices, including surface polarity, pi-conjugation length, architecture, donor-acceptor strength, and interface energy barrier. The recent progress in developing polymer-based charge storage electrets is highlighted in order to provide insights into understanding the operation mechanism and the molecular design-memory properties relationship, as well as improving the overall performance of OFET memory devices.
