- Abstract
Abstract: Neuromorphic optoelectronic devices with new functionality have attracted much attention since they can be applied in energy‐efficient computing and recognition. Here, a silicon optoelectronic device with a designed configuration resembling the retinal circuitry is reported. This kind of device composed of a silicon photoreceptor and a hafnium metal oxide synapse supports optoelectronic spike‐timing‐dependent plasticity that is manipulated completely by both optical and electrical stimuli. The optoelectronic plasticity allows the lasting modulation of photoresponses by using a transient optoelectronic stimulus. Stateful photoresponses can thus be regulated according to either the illumination intensity or the electrical compliance current.
