Article Abstract

An optoelectronic artificial synapse device has been established based on ZnO/Zn-HQ nanoporous hybrid thin films by atomic/molecular layer deposition. This unique nanoporous microstructure in devices significantly enhances the optoelectronic response and relaxation time, enabling important biosynaptic functions under optical stimuli, such as Pavlov's dog experiment and pattern recognition. The mechanism of ionization-deionization of oxygen vacancies has been proposed for this device.

Beijing University of Technology, Key Laboratory of Optoelectronics Technology, School of Information Science and Technology., Beijing, 100124, CHINA.

The rapid advancements in the field of artificial intelligence have intensified the urgent need for low-power, high-speed artificial synaptic devices. Here, a near-infrared (NIR) artificial synaptic device is successfully realized based on pristine InGaAs nanowires (NWs), which achieves a paired-pulse facilitation (PPF) of up to 119%. Additionally, a postsynaptic current (PSC) in memory storage behavior has been implemented by applying different voltage pulses along with continuous illumination of 1064 nm NIR light due to the memristor characteristics of the device.
