A General Strategy for Bandgap Engineering Via Anion‐Lattice Doping in High‐Entropy Oxides

open access: yesAdvanced Science, EarlyView.
A generalizable strategy is developed leveraging facile anion‐lattice doping in high entropy materials to modulate the bandgap in high‐entropy metal oxides (HEMOs). By incorporating nitrogen into a single‐phase high‐entropy metal oxide/nitride (HEMO:HEMN) solid solution, a substantial bandgap reduction from 3.55 eV (HEMO) to ≈2.46 eV (HEMO:HEMN) is ...

Atypical Hydrogen Bond Interaction Enables Anion‐Rich Solvation Structure in Polymer Electrolytes for High‐Voltage Flexible Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
A high‐voltage, Li‐metal‐compatible, and highly conductive polymer electrolyte is reported by integrating a low‐solvating fluorinated plasticizer. Strong atypical hydrogen bonds formed between the plasticizer and polymer chains promote the establishment of anion‐rich solvation structure, effectively stabilizing electrolyte‐electrode interphase at the ...

Unveiling the Corrosion Mechanisms of High‐Entropy RETaO4 Through In Situ Observation

open access: yesAdvanced Science, EarlyView.
Composition‐property relationships in multi‐component RETaO4 are unveiled. In situ XRD/TEM and EBSD expose dynamic crystallization pathways of the dominant corrosion product (pyrochlore) and reaction‐diffusion corrosion mechanisms. La1/6Nd1/6Sm1/6Eu1/6Gd1/6Dy1/6TaO4 emerges as the optimal composition, combining minimal corrosion layer thickness with ...

Ferroelectric Compensation Effect of the Hard Electrode for the HfO2‐ZrO2 Superlattice Films at the Low‐Annealing Temperature

open access: yesAdvanced Electronic Materials, EarlyView.
The hafnia superlattice structure ferroelectric capacitors are clamped by electrodes with various hardness and annealed at 450 to 600 °C. It is found that the out‐of‐plane compressive stress caused by electrode hardness can offset the in‐plane tensile stress loss in hafnium‐based superlattice ferroelectric devices when the annealing temperature ...

Effect of Propagating Dopant Reactivity on Lattice Oxygen Loss in LLZO Solid Electrolyte Contacted with Lithium Metal

open access: yesAdvanced Energy Materials, EarlyView.
The decomposition of Nb‐substituted LLZO solid electrolytes is reported through a propagating reaction between Nb5+ dopants and the Li metal electrode. This work suggests dopants that segregate to interfaces/grain boundaries in LLZO will exhibit reactivity that can propagate into bulk and shed light on new mechanisms for the problematic role of oxygen ...
