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.

具有突触可塑性和状态光响应的基于硅的混合光电器件

具有新功能的神经形态光电器件已引起人们的广泛关注，因为它们可以应用于节能计算和识别中。在此，报道了具有类似于视网膜电路的设计配置的硅光电器件。这种由硅感光体和metal金属氧化物突触组成的装置可支持由光电子刺激定时决定的可塑性，该可塑性完全由光学和电刺激操纵。光电可塑性通过使用瞬态光电刺激实现了光响应的持久调制。因此，可以根据照明强度或电顺应性电流来调节状态光响应。
