Retina-Inspired X-Ray Optoelectronic Synapse Using Amorphous Ga₂O₃ Thin Film.

ABSTRACT: Machine vision techniques are widely applied for object identification in daily life and industrial production, where images are captured and processed by sensors, memories, and processing units sequentially. Neuromorphic optoelectronic synapses, as a preferable option to promote the efficiency of image recognition, are hotly pursued in non-ionizing radiation range, but rarely in ionizing radiation including X-rays. Here, the study proposes an X-ray optoelectronic synapse using amorphous Ga₂O₃ (a-Ga₂O₃) thin film. Boosted by the interfacial V_O ²⁺ defects and its slow neutralization rate, the enhanced electron tunneling process at metal/a-Ga₂O₃ interface produces remarkable X-ray-induced post-synaptic cu
