Analog Weight Update Rule in Ferroelectric Hafnia, Using picoJoule Programming Pulses

Advanced Electronic Materials, EarlyView.
Resistive, ferroelectric synaptic weights based on BEOL‐compatible hafnia/zirconia nanolaminates are fabricated. Lateral downscaling the devices below 10 µm2 enables 20 ns programming with electrical pulses, dissipating ≤ 3 pJ. Experimental results show that final conductance state is set by pulse amplitude, and is largely independent of the initial ...

Dual‐Mode Conductive Hydrogel Sensor Combining Triboelectric and Piezoresistive Mechanisms for Signal Differentiation and Verification

Advanced Electronic Materials, EarlyView.
A hierarchical poly(vinyl alcohol)/polyaniline‐silver nanoparticle hydrogel is developed as a dual‐mode sensor to overcome single‐mechanism limitations. By synchronizing triboelectric and piezoresistive signals, this device differentiates between mechanical touch and environmental moisture, offering high sensitivity and real‐time signal decoupling ...

Enhanced Performance of Optoelectronic Devices Using Metal Chalcogenide Complex Ligands‐Capped InAs/ZnSe Quantum Dots as Electron Transport Layers

Advanced Energy Materials, EarlyView.
Thin‐shell InAs/ZnSe quantum dots functionalized with metal chalcogenide ligands were employed as electron transport layers in organic optoelectronic devices, yielding optimized conduction band alignment and film morphology. Consequently, the devices achieved enhanced charge transport, a detectivity of ∼1013 Jones, and a power conversion efficiency of ...
