説明:

We investigate the role of water in the ferroelectric behavior of networks compris- ing graphene nanoribbons integrated into field effect transistors. We propose that the collective behavior of water molecules influences the system’s dynamics, facilitated by fixed bridging water molecules between the layers and moving clusters formed by sur- rounding molecules. To gain a deeper understanding, we analyze the dependence of the observed phenomena on various factors, including the number of layers, temperature, and the application of external electric fields. Our experimental findings demonstrate that achieving temperature stability in the ferroelectric effect necessitates a minimum bilayer thickness. The experimental results provide compelling evidence for the pres- ence of the remnant field, in line with the findings obtained from the simulations. This study sheds light on the underlying mechanisms governing the ferroelectric behavior in graphene nanoribbons and offers insights for the design of ferroelectric heterostruc- tures and neuromorphic circuits.
