However, very few studies on robust flexible synaptic transistors have been reported, which hold great potential for soft robotics and wearable applications. Here a floating gate synaptic device based on ambipolar black phosphorus (BP) on a flexible substrate has been demonstrated with two working modes. The three-terminal mode, where the carriers are injected into the floating gate, shows a nonvolatile memory effect, whereas the two-terminal mode shows a quasi-nonvolatile memory effect. Remarkably, the synaptic device working on the three-terminal mode shows an excellent performance in the energy-efficient computation of sub-fiScience103947https://www.ebi.ac.uk/biostudies/studies/S-EPMC8904616biostudies-literatureFlexible synaptic floating gate devices with dual electrical modulation based on ambipolar black phosphorus.PMC8904616Li XWang XHu QWu YXiong XfalseFlexible synaptic floating gate devices with dual electrical modulation based on ambipolar black phosphorus.Two-dimensional van der Waals materials offer various possibilities for synaptic devices, matching the requirements of intelligent and energy-efficient computation.
