How to Manufacture Photonic Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

High Photoluminescence Quantum Yield and Tunable Luminescence Lifetimes in the Sub‐Second Range of CaS:Eu2+ Phosphors for Tracer Based Sorting

open access: yesAdvanced Materials Technologies, EarlyView.
Efficient plastic waste sorting is crucial for circularity. Advanced methods using lanthanide photonic tracers enhance recycling beyond near‐infrared sorting. Europium(II)‐doped phosphors, with high stability and long luminescence decay, improve tracer detection in sorting systems, enabling precise identification of different plastic materials ...

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.
