SnO₂-Based Optoelectronic Synapses for Artificial Visual Applications

Abstract Optoelectronic synapse units have been drawing a strong interest lately due to their obvious crucial role in the evolution of optoelectronic integration-based neuromorphic computing. Here, synaptic devices are fabricated based on stannic oxide (SnO 2 ) film and with structure ITO/SnO /P ++ -Si. Using optical stimulation, we found that sandwich highly responsive exhibit fast switching behavior. These optically stimulated accurately could imitate functions, including paired-pulse facilitation (PPF), excitatory postsynaptic current (EPSC), learning experience behavior, conversion from short-term memory (STM) long-term (LTM). The EPSC such be tuned via light, contributing an LTM-based analog enhancing across affective situations. work presented here advances research manufacture synapses SnO thin films for computing applications.
