Abstract

Neuromorphic computing systems that are capable of parallel information storage and processing with high area and energy efficiencies, offer important opportunities for future storage systems and in-memory computing. Here, it is shown that a carbon dots/silk protein (CDs/silk) blend can be used as a light-tunable charge trapping medium to fabricate an electro-photoactive transistor synapse. The synaptic device can be optically operated in volatile or nonvolatile modes, ensuring concomitant short-term and long-term neuroplasticity. The synaptic-like behaviors are attributed to the photogating effect induced by trapped photogenerated electrons in the hybrid CDs/silk film which is confirmed with atomic force microscopy based electrical techniques. In addition, system-level pattern recognition capability of the synaptic device is evaluated by a single-layer perceptron model. The remote optical operation of neuromorphic architecture provides promising building blocks to complete bioinspired photonic computing paradigms.
