HZO/HSO Superlattice ReFET Array Integrating Optical Sensing for Neuromorphic Vision Computing.

ABSTRACT: Neuromorphic vision systems require artificial synapses that integrate sensing, memory, and computation with high precision and stability. Conventional memristors face limitations including forming requirements, few multilevel states, low endurance, and poor integration density, while ferroelectric and flash-based transistors suffer trade-offs among endurance, retention, and switching ratio, and generally lack intrinsic photonic sensitivity, constraining in-sensor computing. Here, a photonic resistive-gate field-effect transistor (ReFET) array is presented that combines optical sensing, forming-free multilevel memory, and analog computation in a single device. The ReFET employs a Hf₀.₅Zr₀.₅O₂/Hf₀.₉₅Sr₀.
