On‐Chip Silicon‐Based Micro‐Reflector Pixelated with Micro‐Light‐Emitting Diodes for Augmented Reality Projection Displays

open access: yesAdvanced Science, EarlyView.
This paper presents a pixel‐by‐pixel on‐chip silicon‐based micro‐reflector device (SMRD) for µLEDs that enables simultaneous light‐extraction enhancement and directional emission control. The scalable architecture significantly improves forward light utilization and suppresses pixel crosstalk.

Multi‐Force‐Driven Self‐Recoverable SWIR Mechanoluminescence for Underwater Communication

open access: yesAdvanced Science, EarlyView.
This study represents the first demonstration of self‐recoverable mechanoluminescent (ML) within a single material across diverse mechanical modes, enabled by the synergistic coupling of piezoelectric and triboelectric effects. Through a combinatorial doping approach, the MgNb2O6 crystal exhibits breakthrough short‐wavelength infrared ML performance ...

Unlocking Ferroelectricity in Scalable AlBN Films via Plasma‐Enhanced Atomic Layer Deposition

open access: yesAdvanced Electronic Materials, EarlyView.
This study presents the CMOS‐compatible plasma‐enhanced atomic layer deposition of AlBN ferroelectric thin films and demonstrates clear polarization‐switching behavior. By elucidating the B‐incorporation pathway through DFT calculations and correlating structural evolution with PFM and P–E measurements, the study supports AlBN as a promising nitride ...
