Optoelectronic synapse based on the optical response of Ga2O3. a Schematic depiction of the human visual system, including image sensing, memory, and processing, as well as an Ag/Ga2O3/Pt synaptic device. b PSC responses are activated by two consecutive UV light pulses. c PPF index fitting results plotted by pulse intervals Δt. d The variations of PSC in 20 cycles of different Δt (3 s–15 s). The transformation from STM to LTM in PSC. e intensity, (f) number of light pulses, (g) duration, (h) frequency. (UV light: 254 nm)
