 Abstract optoelectronic synaptic devices integrating light perception and signal storage functions have been developed with the aim of achieving neuromorphic computing for visual information processing, complex brain light learning, memorization, and reasoning. These devices were grown on gold nanorot arrays, which served as guides for precursor nucleation. Characterizations of the resulting monolayer MOS2 arrays showed that they were homogenous single layers and were further fabricated into optoelectronic devices. The devices exhibited photo currents and optical responses and were used to study the behavior of synapses under different light stimulation. This behavior was modeled after the brain's ability to store and retrieve information and included features such as short-term potentiation, long-term potentiation, and paired pulse facilitation. Additionally, a visual sensing system was constructed from five by six pixels, which simulated the light sensing capabilities of the brain. Finally, this system was able to use associated images to restore vague or incomplete memories, demonstrating the ability of these devices to mimic human intelligent behaviors.
