XHEMTs on Ultrawide Bandgap Single‐Crystal AlN Substrates

open access: yesAdvanced Electronic Materials, EarlyView.
AlN/GaN/AlN XHEMTs [single‐crystal (“X‐tal”) high‐electron‐mobility transistors] are built on bulk AlN substrates with a 20 nm pseudomorphic GaN channel. This coherent epitaxial double heterostructure promises low‐defect, thermally efficient nitride electronics for next‐generation RF technology.

Phonons in Single‐Domain κ‐Ga2O3 Studied by Polarization Angle‐Resolved Raman Scattering

open access: yesAdvanced Electronic Materials, EarlyView.
Single‐domain κ‐Ga2O3 is systematically studied using advanced Raman spectroscopy, revealing over 100 Raman‐active phonon modes. These modes are compared with theoretical predictions and organized within a newly established nomenclature, offering a robust reference for future research.

Robust C–V Ratio Technique for Profiling Defects in Proton‐Irradiated 4H‐SiC

open access: yesAdvanced Electronic Materials, EarlyView.
A noise‐robust C–V ratio technique is introduced to profile radiation‐induced defects in proton‐irradiated 4H‐SiC Schottky diodes. By using analytical capacitance ratios instead of numerical differentiation, the method directly extracts trap‐density and effective trap‐energy profiles at room temperature.

Effect of Gate Length Relative to Recess Coverage on the Performance of Enhancement‐Mode β‐Ga2O3 MOSFETs

open access: yesAdvanced Electronic Materials, EarlyView.
Gate‐length engineering in recessed‐gate enhancement‐mode β‐Ga2O3 metal‐oxide‐semiconductor filed effect transistors was investigated by extending the gate to fully cover the etched recess. Complete recess coverage improves electrostatic control, reduces series resistance, shifts the threshold voltage positively, and enhances mobility, on‐resistance ...

Degradation Mechanism of Phosphate‐Based Li‐NASICON Conductors in Alkaline Environment

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The presence of water in the cathode of a Li‐air battery shifts reactions to produce LiOH, creating a corrosive, alkaline environment. This study investigates the alkaline stability of the common Li‐NASICON solid‐state conductor chemistries through a systematic experimental study combined with computational modeling to understand the degradation ...
