ZnO Quantum Dots@CsPbBr₃ Poly-Heterocrystalline Film Enables High-Performance Floating-Gate Transistor Arrays for Edge Computing.

ABSTRACT: Nonvolatile optoelectronic synapses motivated by the human eye can effectively function as convolutional kernels to preprocess images, demonstrating significant promise for edge computing. Among the optoelectronic synapses, the floating-gate photosensitive transistor (FG-PT) is particularly noteworthy due to its rapid response speed and excellent retention. Although some FG-PTs are reported, they still suffer from high operating voltages, low conductance ratios, and difficulties in array preparation. Here, a ZnO QDs@CsPbBr₃ poly-heterocrystalline (PHC) film to serve as the floating gate layer of FG-PT is synthesized. The PHC film combines the desirable properties of each phase, exhibiting both high electrical conductivity and excellent photoelectric properties. The high electric
