Noise‐Tunable Memristor Enabling Programmable Probabilistic Neurons for Frequency‐Selective Time‐Series Signal Encoding

open access: yesAdvanced Materials, EarlyView.
Memristors offer tunable resistance and intrinsic instability, making them promising tunable noise sources. We propose a spiking‐rate‐programmable probabilistic neuron using a Ru/TaOx/Pt memristor, where resistance‐dependent noise enables frequency‐selective encoding.

Direct Growth of 2D Bilayers on Au(111) for Low‐Coercive Sliding Ferroelectricity

open access: yesAdvanced Materials, EarlyView.
Controlled CVD growth of stacking‐defined bilayer ReS2 on Au(111) enables parallel‐stacked bilayers with intrinsic sliding ferroelectricity, a strong piezoelectric response, and an ultralow coercive voltage. Atomic‐resolution imaging and in situ measurements further reveal the decisive role of clean interfaces in achieving low‐barrier ferroelectric ...

Confinement‐Induced Donnan Potential Enables Sealed Hydrovoltaic Power From Microliter Water

open access: yesAdvanced Materials, EarlyView.
An ultrathin MXene/cellulose nanofiber (CNF) nanochannel‐based hydrovoltaic generator produces sustained direct current (DC) from a single microliter droplet under sealed operation. Asymmetric nanochannel confinement establishes a persistent ion gradient and a confinement‐induced Donnan potential, harvesting the interfacial free energy released upon ...

Measuring and Manipulating Density of States in Two‐Dimensional Materials With Electrochemical Capacitance

open access: yesAdvanced Materials Interfaces, EarlyView.
We report electrochemical quantum capacitance spectroscopy as an ambient, in situ probe for defect‐mediated electronic structure at 2D material interfaces. Using monolayer MoS2, the method resolves band edges and vacancy states, tracks sulfur‐vacancy evolution during hydrogen evolution, and links interfacial density‐of‐states changes to nearly ...

Enhancing Performance and Reliability of Hf1‐xZrxO2 Morphotropic Phase Boundary Films via Nanolaminate Structuring and Microwave Annealing

open access: yesAdvanced Materials Technologies, EarlyView.
Hf–Zr–O‐based morphotropic phase boundary (MPB) thin films often suffer from limited endurance and poor uniformity due to intrinsic phase instability. This work proposes a nanolaminate architecture that spatially separates competing phases, stabilizes phase formation, and suppresses wake‐up‐induced degradation.
