Memtransistors composed of 2D van der Waals (vdW) heterostructures are crucial for constructing artificial synaptic devices and realizing neuromorphic computing. The functional integration containing ultralow power, nonvolatile memory, biomimetic behavior endows such with broad prospects. Here, we develop an optoelectronic memtransistor based on the WS2/In2Se3 vdW heterostructure realize significant optical electrical properties, which can simulate both short-range plasticity (STP) long-range (LTP) biological synapses. Under stimulation, device demonstrates power consumption (only 7.7 aJ per spike) significantly lower than synapses, indicating application potential in large-scale hardware. Combining stimuli, perform multiple logic operations by controlling inputs WS2/In2Se3-based memtransistor. Besides, simulated recognition utilizing Modified National Institute Standards Technology data set achieve a accuracy 85.41%. Notably, this remain above 80% even introduction Gaussian noise. These results demonstrate promising memtransistors future
