제목 Ferroelectric non-volatile memory with highly aligned polymer nanowire
초록 We demonstrated a novel polymer NW ferroelectric field effect transistor (Fe-FET) with a position-addressable semiconducting polymer NW channel and ferroelectric polymer insulator. The direct electrohydrodynamic NW printing was employed to develop large-scale assembly of highly aligned semiconducting poly(3-hexylthiophene) (P3HT) NWs, allowing for precise control of location as well as number of NWs between source and drain electrode. Memory performance was systematically investigated as a function of the number of NWs in the channel regions. Our polymer NW Fe-FETs with carefully controlled NW/ferroelectric polymer interface exhibited large ON/OFF current margin of approximately 102 with time-dependent data retention and read/write endurance of more than 104 seconds and 102 cycles, respectively. Furthermore, they are mechanically flexible, and thus suitable for multiple bending circumstance.
