제목 High-performance polyimide bearing diphenylaminobenzylidenylimine moieties which exhibit excellent nonvolatile memory characteristics.
초록 A new high-performance polyimide (PI), poly(3,3′-di(4-(diphenylamino)benzylidenyliminoethoxy)-4,4′biphenylenehexafluoroisopropylidenediphthalimide) (6F-HAB-TPAIE PI) is dimensionally stable up to 280 °C and thermally stable up to 440 °C. In devices fabricated with the PI polymer as an active memory layer, the active PI polymer was found to operate at less than ±2 V in electrically bistable unipolar and bipolar switching modes by controlling the compliance current. The PI polymer layer exhibits repeatable writing-reading-erasing capability with high reliability in ambient air conditions as well as at high temperatures up to 130 °C. The observed nonvolatile memory behaviors are due to Schottky emission and local filament formation.
