Electro‐Chemo‐Mechanical Coupling in Hf0.5Zr0.5O2 Ferroionic Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
Schematic of a ferroionic HZO heterostructure where epitaxial interfaces enable dynamic oxygen‐vacancy exchange, coupling ionic and ferroelectric degrees of freedom. Vacancy‐mediated polarization modulation biases HZO polymorphism, suppresses leakage, and enhances piezoelectric response, yielding distinct butterfly‐loop evolution and diode‐like ...

Identifying the True Willingness-To-Pay of Bayesian Respondents in a Dichotomous Choice Contingent Valuation Methodology [PDF]

open access: yes
This paper develops a respondent model of Bayesian updating for a double-bound dichotomous choice (DB-DC) contingent valuation methodology. We demonstrate by way of data simulations that current DB-DC identifications of true willingness-to-pay (WTP) may ...

Molecularly Engineered Highly Stable Memristors with Ultra‐Low Operational Voltage: Integrating Synthetic DNA with Quasi‐2D Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
Molecularly engineered memristors integrating Ag nanoparticle–embedded synthetic DNA with quasi‐2D halide perovskites enable ultra‐low‐operational voltage, forming‐free resistive switching, and record‐low power density. This synergistic integration of customized DNA and 2D OHP in bio‐hybrid architecture enhances charge transport, reduces variability ...

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Permeability Macromodels for Magnetic Powder Materials Under DC Bias

open access: yesIEEE Transactions on Power Electronics
Magnetic powder materials are often considered for inductors used in high-current applications due to their high saturation flux densities and good high-frequency performance. For the design and optimization of powder-based high-frequency inductors, it is important to consider permeability spectra with superimposed DC bias.

Uncovering the Origin of Efficiency Roll‐Off in TADF OLEDs

open access: yesAdvanced Functional Materials, EarlyView.
OLEDs based on thermally activated delayed fluorescent (TADF) materials often suffer from a severe drop in efficiency at high brightness levels. This work presents a technique to uncover the source of this efficiency drop, and quantifies the exciton‐exciton and exciton‐polaron annihilation processes responsible for efficiency losses in our TADF OLEDs ...
