Superior Adhesion of Monolayer Amorphous Carbon to Copper

Advanced Materials, EarlyView.
The adhesion energy of monolayer amorphous carbon on copper substrate is 85 J m−2, 13 times higher than that of graphene due to covalent‐like bonding between the sp2 carbon structure to copper. X‐ray photoelectron spectroscopy (XPS), near‐edge X‐ray absorption (NEXAFS), and (density functional theory) DFT calculations are used to elucidate the ...

Dynamic Magnonic Crystals Based on Spatiotemporal Plasmon Excitation

Advanced Materials, EarlyView.
Hybrid magnonic‐plasmonic metamaterials enabling spatiotemporal optical control of spin‐wave transport are demonstrated. These structures integrate periodic stripes of gold nanodisk arrays with low‐damping yttrium iron garnet films to realize dynamically reconfigurable magnonic crystals.
