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.
