Epitaxial Growth of p‐Type β‐Ga2O3 Thin Films and Demonstration of a p–n Diode

Advanced Electronic Materials, EarlyView.
This study demonstrates p‐type conductivity in β‐Ga2O3 via Te–Mg co‐doping using MOCVD. The films show tunable hole concentrations up to 1.78×1017 cm−3, and a fabricated p–n diode exhibits rectifying behavior. Density functional theory reveals that Te introduces an intermediate band, lowering the Mg acceptor ionization energy and enabling p‐type ...

Carrier Transport and Electrical Bandgaps in Epitaxial CrN Layers

Advanced Electronic Materials, EarlyView.
ABSTRACT The transport properties and electrical bandgap of nominally undoped ≈$\approx$75‐nm‐thick CrN layers simultaneously grown on AlN(0001) and AlN(112¯$\bar{2}$2) templates using plasma‐assisted molecular beam epitaxy are investigated. The layers grown on AlN(0001) and AlN(112¯$\bar{2}$2) exhibit (111) and (113) surface orientations, respectively.

Comparative Insights and Overlooked Factors of Interphase Chemistry in Alkali Metal‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review presents a comparative analysis of Li‐, Na‐, and K‐ion batteries, focusing on the critical role of electrode–electrolyte interphases. It especially highlights overlooked aspects such as SEI/CEI misconceptions, binder effects, and self‐discharge relevance, emphasizing the limitations of current understanding and offering strategies for ...

Stage‐Specific Roles of Deep Eutectic Solvents in Recycling of Spent Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Deep eutectic solvents (DESs) offer tunable acidity, redox, and coordination properties for selective recycling of spent lithium‐ion battery cathodes. Through co‐dissolution, single‐ and two‐metal separations, DESs enable sustainable recovery of critical metals for closed‐loop regeneration of battery‐grade materials, advancing a circular economy for ...
