Reliable Bi-Layer HfO2/Zr-Doped ZnO Memristive Synaptic Devices

Oxide-based memristive synaptic devices are promising hardware elements for neuromorphic computing, but stochastic resistive switching caused by uncontrolled defect distributions and localized conductive paths remains a critical challenge. Here, we demonstrate Zr-doped ZnO memristive synaptic devices fabricated using a...

Enhanced Reliability and Neuromorphic Functionality of a-IGZO-Based Memristors via N2 Annealing-Induced Vacancy Modulation.

Amorphous indium-gallium-zinc oxide (a-IGZO)-based memristors have attracted considerable attention for neuromorphic computing applications owing to their structural uniformity, amorphous-phase stability, CMOS compatibility, and oxygen-vacancy-mediated resistive switching characteristics. However, uncontrolled oxygen-v...
