Transfer printing of metal nanoring and nanodot arrays for use in catalytic reactions.

The fabrication of periodic metal nanodot arrays through pulsed laser melting induced fragmentation of metal nanogratings.

We propose and demonstrate a new method for fabricating periodic arrays of metal nanodots over a large area. In this method, metal nanogratings were first patterned on a substrate by nanoimprint lithography and lift-off, and were then melted using a single excimer laser pulse. We found that the laser melting broke the metal nanogratings into periodic nanodots. Furthermore, we demonstrated the c...

Laser-fabricated porous alumina membranes (LF-PAM) for the preparation of metal nanodot arrays

In situ fabrication of ordered nanoring arrays via the reconstruction of patterned block copolymer thin films.

We report a novel and versatile approach for fabricating ordered nanoring arrays of metals, metal oxides, and other inorganic materials with diameter of sub-50 nm by loading the salt precursors in P4VP cores of PS-b-P4VP thin film and exposing these to methanol vapor which results in the P4VP blocks shrinking to form nanorings.

Lithographically patterned electrodeposition of gold, silver, and nickel nanoring arrays with widely tunable near-infrared plasmonic resonances.

A novel low-cost nanoring array fabrication method that combines the process of lithographically patterned nanoscale electrodeposition (LPNE) with colloidal lithography is described. Nanoring array fabrication was accomplished in three steps: (i) a thin (70 nm) sacrificial nickel or silver film was first vapor-deposited onto a plasma-etched packed colloidal monolayer; (ii) the polymer colloids ...

Ultranarrow band absorbers based on surface lattice resonances in nanostructured metal surfaces.

Nanostructured metals have received a significant amount of attention in recent years due to their exciting plasmonic and photonic properties enabling strong field localization, light concentration, and strong absorption and scattering at their resonance frequencies. Resonant plasmonic and metamaterial absorbers are of particular interest for applications in a wide variety of technologies inclu...
