two-dimensional heterostructures are promising synaptic materials for photonic synapses. by using artificial photosensitive synapses, neuromorphic electronics such as bionic eyes can emulate biological nervous systems with in-memory sensing and computing abilities.

recently, researchers from chinese academy of sciences and nanjing tech university have demonstrated a facile interfacial coassembly of a large-area photosensitive heterobilayer. they utilized it as an optoelectronic converter for neuromorphic electronics.

the heterobilayer was assembled from graphene oxide and perylene at the liquid-liquid interface, with the merits of centimeter-scale, high uniformity and broadband absorption from visible to near-infrared regions.

these characters ensure the exceptional photoperception of planar heterostructure devices. specifically, this heterosynapse as an artificial neuron can be implemented into a neuromorphic network that is capable of visual learning and recognition.

the technology can therefore be helpful for the future applications of artificial intelligence technologies including autonomous driving.
