The authors study plasmonic enhancements of photoluminescence (PL) in Si nanodisk (ND) arrays hybridized with nanostructures such as nanoplates of Au, where these hybrid nanostructures are fabricated by fully top-down lithography: neutral-beam etching using bio-nano-templates and high-resolution electron-beam lithography. The separation distance between the Si ND and Au nanostructure surfaces i...

Abstract Magnetic nanodisks have been recently proposed as biomedical tools for therapeutics at the nanoscale level, with a special focus on hyperthermia cancer cure. Here we present detailed study of permalloy to be used in alternative superparamagnetic iron oxide nanoparticles, efficient heating agents that release heat via magnetic hysteresis. A micromagnetic modeling analysis is carried out...

Skyrmion bags are composed of an outer skyrmion and arbitrary inner skyrmions, which have recently been observed in bulk chiral magnets, but still remain elusive magnetic films. Here, we propose a method creating thin-film nanodisk, includes three steps. Firstly, the size is enlarged by vertical field, then skyrmions nucleated at off-center area local current injection, system finally reconstru...

Lithium niobate (LN) is a promising optical material, its micro–nano structures have been applied to fields such as photonic crystals, nonlinear optics, waveguides, and so on. At present, lithium structural colors are rarely studied. Although the nanograting structure was researched, it has large full width at half-maximum (fwhm) that cannot achieve red, green, or blue pixels other high-saturat...
