Controllable Resistive Switching in ReS₂ /WS₂ Heterostructure for Nonvolatile Memory and Synaptic Simulation.

ABSTRACT: Memristors with nonvolatile storage performance and simulated synaptic functions are regarded as one of the critical devices to overcome the bottleneck in traditional von Neumann computer architecture. 2D van der Waals heterostructures have paved a new way for the development of advanced memristors by integrating the intriguing features of different materials and offering additional controllability over their optoelectronic properties. Herein, planar memristors with both electrical and optical tunability based on ReS₂ /WS₂ van der Waals heterostructure are demonstrated. The devices show unique unipolar nonvolatile behavior with high R_off /R_on ratio of up to 10⁶ , desirable endurance, and retention, which are superior to pure ReS_2<
