The fabrication of nanopatterns with Au nanoparticles-embedded micelles via nanoimprint lithography.

We fabricated nanopatterns with Au nanoparticles-embedded micelles (Au-micelles) by self-assembly of block copolymers via nanoimprint lithography. The micelle structure prepared by self-assembled block copolymers was used as a template for the synthesis of Au nanoparticles (Au NPs). Au NPs were synthesized in situ inside the micelles of polystyrene-block-poly(2-vinylpyridine) (PS- b-P2VP).

Templated assembly of metal nanoparticles in nanoimprinted patterns for metal nanowire fabrication.

We have developed a new method that combines nanoimprint lithography and metal nanoparticle solution processing for fabricating metal nanowires. A polymer template with nanoscale features, fabricated by nanoimprint lithography, provided physical reservoirs which were filled with a silver nanoparticle solution during the spin-coating. After the lift-off process, the defined silver nanoparticle patterns were annealed to enhance the conductivity for use as electrodes.

Fabrication of imprint stamp by using nanosphere lithography and its utilization to photoluminescence enhancement.

Nanosphere lithography is proposed as a new technique for the fabrication of nanoscale pillars on p-GaN layer. This technique is an easy and simple process using a self-assembled monolayer of spheres, which act as etching masks to form pillars on a Si3N4 substrate, that could be utilized as a stamp for UV-based imprint lithography. We can apply the UV-based imprint technique in the field of solid-state lighting in order to extract more lights to out-world by texturing the outer surface of the light emitting diodes (LED) structure.
