Opto‐Ferroelectric Coupling Enhanced α‐In 2 Se 3 Transistors With Light‐Controlled Mode Switchover

is significantly enhanced, leading to an enlarged hysteresis window (ΔV) and switching the transistor into an optoelectronic synapse mode for neuromorphic computing, which can support image classification with an accuracy of up to 94.43% and a low energy consumption of 0.47 pJ/spike. This work provides an opto-ferroelectric coupling-enhanced transistor that addresses the incompatibility issue between digital logic and neuromorphic computing units, offering a new pathway for next-generation computing devices.
