Mimicking neuroplasticity in a hybrid biopolymer transistor by dual modes modulation
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 inâmemory computing. Here, it is shown that a carbon dots/silk protein (CDs/silk) blend can be used as a lightâtunable charge trapping medium to fabricate an electroâphotoactive transistor synapse. The synaptic device can be optically operated in volatile or nonvolatile modes, ensuring concomitant shortâterm and longâterm neuroplasticity. The synapticâlike 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, systemâlevel pattern recognition capability of the synaptic device is evaluated by a singleâlayer perceptron model. The remote optical operation of neuromorphic architecture provides promising building blocks to complete bioinspired photonic computing paradigms
