Reliable fabrication of micro/nanostructures with sub-10 nm features is of great significance
for advancing nanoscience and nanotechnology. While the capability of current …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Optimization techniques have been indispensable for designing high-performance meta-
devices targeted to a wide range of applications. In fact, today optimization is no longer an …

Hybrid nanostructures composed of graphene or other two-dimensional (2D) nanomaterials
and plasmonic metal components have been extensively studied. The unusual properties of …

Free electron beams such as those employed in electron microscopes have evolved into
powerful tools to investigate photonic nanostructures with an unrivaled combination of …

When two metal nanostructures are placed nanometres apart, their optically driven free
electrons couple electrically across the gap. The resulting plasmons have enhanced optical …

This review provides a broad overview of the studies and effects of nonlocal response in
metallic nanostructures. In particular, we thoroughly present the nonlocal hydrodynamic …

Predetermined and selective placement of nanoparticles onto large-area substrates with
nanometre-scale precision is essential to harness the unique properties of nanoparticle …

Plasmonic gap nanostructures (PGNs) have been extensively investigated mainly because
of their strongly enhanced optical responses, which stem from the high intensity of the …

We investigated electron-beam lithography with an aberration-corrected scanning
transmission electron microscope. We achieved 2 nm isolated feature size and 5 nm half …
