Design of two-dimensional halide perovskite composites for optoelectronic applications and beyond

“…Recently, biomimetic artificial synapses have made great progress, in which the two-port memristor has the advantages of simple structure and good integration, regarded as an ideal carrier of bionic synapses. 204 The counterion of halide perovskite is movable under electric field, which makes it very promising in the memristor field. Based on the excellent light absorption capacity of perovskites, these memristors can also provide novel functions through the collaborative coupling of photon, electron and ion processes.…”

An Artificial Synapse Based on CsPbI3 Thin Film

“…Peaks from the δ-phase can be seen from the X-ray diffraction (XRD) pattern [21]. As shown in Figure 1, the crystal phases of diffraction peaks at 21.8 degrees, 22.7 degrees, 26.6 degrees, 27.5 degrees, 30.3 degrees, and 37.6 degrees are (014), (023), (015), (032), (016), and (134), respectively.…”

A carbon conductive filament-induced robust resistance switching behavior for brain-inspired computing

“…5,6 As a class of qualified synaptic devices, two-terminal memristors with similar structures and functional principles to neural synapses are considered the most favorable candidates for breaking through the von Neumann framework. 7,8 As emerging memory devices, memristors have many irreplaceable advantages while still having drawbacks. Conventional electrochemical metal memristors (ECM) can be characterized as a class of classical biomimetic devices whose switching behavior is triggered by the formation and rupturing of conductive filaments made up of active metals (Ag, Cu, etc.).…”
