Performance Enhancement in Hafnium Oxide Through Homogeneous and Heterogeneous co‐Doping Strategies

open access: yesAdvanced Electronic Materials, EarlyView.
This article presents a comprehensive co‐doping toolkit to optimize the performance and reliability of fluorite‐structure ferroelectrics like hafnium oxide. By employing homogeneous and heterogeneous co‐doping strategies, precise control over crystallization behavior, polarization hysteresis, and oxygen vacancy distribution is achieved.

Wafer‐Scale Bi2O2Se‐on‐Insulator Thin Films for Integrated Electronics

open access: yesAdvanced Electronic Materials, EarlyView.
Wafer‐scale, thickness‐controlled semiconducting Bi2O2Se thin films were grown on 2‐inch insulating sapphire substrates via magnetron sputtering using quasi‐van der Waals epitaxy. The uniform films enable large‐scale fabrication of top‐gated TFT arrays with stable enhancement‐mode operation and functional inverter, NAND, and NOR logic gates.

Amazing Grazing: N use efficiency of 60 individual dairy cows under intensive grazing

open access: yes, 2018
The Dutch dairy sector aims to improve nitrogen (N) use efficiency (NUEN) of intensive dairy farms while supporting grazing. To gain insight into the NUEN of intensive dairy farms, we need insight into the NUEN at cow level. We performed a 2 x 2 factorial grazing trial with 60 Holstein Friesian cows (7.5 cows ha-1), in which we compared NUEN of ...

Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Toward a Rational Design of Conjugated Copolymers with Oxygenated Side Chains for Boosting Thermoelectric Properties

open access: yesAdvanced Energy Materials, EarlyView.
The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...
