“…1(f) and Table S1 (ESI†). The E for each photosynaptic event is calculated by the following formula: 46 Δ E = V × I × Δ t where V is the voltage applied to both ends of the device; I represents the peak value of the EPSC after one light pulse, and Δ t is the optical pulse width. The power consumption and S of the device prepared in this study are among the best parameters for the reported optoelectronic synapse.…”

High‐temperature resistant solar‐blind optoelectronic synapse has a significant demand such as aerospace and fire warning, which integrates sensing and processing functions to realize complex functions like learning, recognition, and memory. However, developing such device remains a tremendous challenge. Herein, a two‐terminal GaOX solar‐blind optoelectronic synapse with high‐temperature working ability is proposed, and it is applied to neuromorphic computing and cryptography. Benefiting from the high internal gain, the device can detect the light intensity of nW cm−2, displaying one of the best figures‐of‐merit in solar‐blind photodetectors. Furthermore, the device possesses remarkable image sensing and memorization ability because of its ultrasensitive light detection ability and prominent synapse performance resulting from large charge trapping states density. Simultaneously, the device shows undamped photodetection and synaptic performances even at 610 K, reflecting a high‐temperature endurance and a desired property for practical applications under harsh environment. Moreover, by constructing an artificial neural network, high‐precision recognition of handwritten digits are realized under 610 K. A photosynaptic array with 12 × 12 pixels is constructed, and it is applied in cryptography that enables simultaneous sensing and encryption in the same devices. This work is expected to drive the progress of Ga2O3 in harsh environment.

Manipulating the expression of synaptic plasticity of neuromorphic devices provides fascinating opportunities to develop hardware platforms for artificial intelligence. However, great efforts have been devoted to exploring biomimetic mechanisms of plasticity simulation in the last few years. Recent progress in various plasticity modulation techniques has pushed the research of synaptic electronics from static plasticity simulation to dynamic plasticity modulation, improving the accuracy of neuromorphic computing and providing strategies for implementing neuromorphic sensing functions. Herein, several fascinating strategies for synaptic plasticity modulation through chemical techniques, device structure design, and physical signal sensing are reviewed. For chemical techniques, the underlying mechanisms for the modification of functional materials were clarified and its effect on the expression of synaptic plasticity was also highlighted. Based on device structure design, the reconfigurable operation of neuromorphic devices was well demonstrated to achieve programmable neuromorphic functions. Besides, integrating the sensory units with neuromorphic processing circuits paved a new way to achieve human-like intelligent perception under the modulation of physical signals such as light, strain, and temperature. Finally, considering that the relevant technology is still in the basic exploration stage, some prospects or development suggestions are put forward to promote the development of neuromorphic devices.
