Direct Integration of Polycrystalline Diamond With 3C‐SiC for Enhanced Thermal Management in GaN HEMTs: Impact of Grain Structure and Interface Engineering

open access: yesAdvanced Materials Technologies, EarlyView.
Polycrystalline diamond (PCD) is directly bonded to 3C‐SiC for GaN HEMTs on a 2‐inch wafer using an advanced room‐temperature process. Despite high thermal conductivity at the growth surface, phonon scattering at the fine‐grained nucleation side raises thermal resistance.

Investigation of Exothermic Behaviors of Energetic Particles in Microfluidics Channels

open access: yesAdvanced Materials Technologies, EarlyView.
Scheme and representative frames of delivery, ignition, and combustion process of core@shell Al@CuO energetic material in a microchannel. The electrical discharge occurred at the throat of microchannel leads to the combustion of the energetic reaction, causing the formation of high‐momentum butterfly‐shaped jet at the throat.

Asymmetric Transmission and Diffraction Engineering in Ultrathin media via Coupled Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Grating‐insulator‐grating coupled crosstalking metasurfaces hosted on a silicon nitride membrane platform for asymmetric control of the diffraction pattern and asymmetric transmission. It is shown that exploiting the interferences of higher diffraction orders between the two metasurfaces and engineering the resulting modes enables AT in such ...

Magnetic Steganography Based on Wide‐Field Diamond Quantum Microscopy

open access: yesAdvanced Optical Materials, EarlyView.
This document illustrates magnetic steganography. Magnetic graphics, including pixel art and QR codes, are produced using magnetic materials (such as Ni) and obscure behind patterns manufactured using non‐magnetic materials (such as Au), which are unveiled through widefield quantum microscopy. Furthermore, manipulating the electron spin of NV with dual
