Recently, organic neuromorphic devices are a very active topic of research. However, the neuromorphic devices studied cannot be regarded as unique multifunctional devices because all built-in functions are mutually combined. To address this, we focus on the separation of electrical switching and data storage functions in organic ferroelectric memory transistors. A study was conducted to create a multifunctional neuromorphic device by mixing P(VDF-TrFE) (poly(vinylidene flurodie-trifluoroethylene)), a ferroelectric polymer, and photocrosslinker (bis-perfluorobenzoazide). High permittivity needed for electrical switching and the ferroelectricity needed for data storage become compatible by restricting the motion of P(VDF-TrFE) via photocrosslinking. We show that the properties of devices can be controlled by mixing different concentrations of photocrosslinker, and presents a breakthrough direction in the study of multifunctional neuromorphic devices. |
