Opposite Trap‐State Evolution Pathways Govern Endurance and Retention Failure in Amorphous Chalcogenide Memory

open access: yesAdvanced Science, EarlyView.
GeSbSe selector‐only memory devices are investigated through physical and electrical analyses to reveal opposite trap‐state evolution pathways governing reliability degradation. Endurance cycling drives Se migration, transitioning traps from deep to shallow states.

Enhancing Specific Stiffness of Nano‐Architected Materials Through Generative AI and Active Learning

open access: yesAdvanced Science, EarlyView.
A structure‐centric generative framework searches voxelated design space directly, coupling a variational autoencoder with multi‐objective optimization and active learning to progressively expand the validated design domain. The discovered nano‐architectures, realized as pyrolytic carbon by two‐photon lithography, deliver 18–23% higher stiffness and 26–

Lattice Disorder in CuI Enables Filament‐Free Transparent Memristors

open access: yesAdvanced Science, EarlyView.
Transparent Cu1‐xAgxI thin‐film memristors rely on internal ion transport to produce reversible resistive‐switching effects. Direct elemental characterizations observe obvious Cu and Ag redistribution driven by applied bias, proving mobile ions drive the device's resistive‐switching responses.
