제목 Multi-bit Non-volatile Polymer Memory with Solution-blended Ferroelectric Polymer Insulators for Low Voltage Operation
초록 We present a low voltage operating Multi-bit polymer Fe-FET memory with a high k ferroelectric polymer insulator. Effective enhancement of capacitance of the ferroelectric gate insulator layer was achieved by a simple binary solution-blend of a ferroelectric poly(vinylidene fluoride-co-trifluoroethylene) (PVDF-TrFE) (k~8) with a relaxer high-k poly(vinylidene-fluoride–trifluoroethylene–chlorotrifluoroethylene) (PVDF-TrFE-CTFE) (k~18). At optimized conditions, a ferroelectric insulator with a PVDF-TrFE/PVDF-TrFE-CTFE (10/5) blend composition enabled the discrete six-level multi-state operation of a Multi-bit Fe-FET at a gate voltage sweep of 18 V with excellent data retention and endurance of each state of more than 104 seconds and 120 cycles, respectively.
