Negative index fishnet with nanopillars formed by direct nano-imprint lithography
In this paper we demonstrate the ability to fabricate fishnets by nanoimprinting directly into a pre-deposited three layer metal–dielectric–metal stack, enabling us to pattern large areas in two minutes. We have designed and fabricated two different fishnet structures of varying dimensions using this method and measured their resonant wavelengths in the near-infrared at 1.45 μm and 1.88 μm. An ...
متن کامل3D Simulation of Nano-Imprint Lithography
A proof of concept study of the feasibility of fully three-dimensional (3D) time-dependent simulation of nano-imprint lithography of polymer melt, where the polymer is treated as a structured liquid, has been presented. Considering the flow physics of the polymer as a structured liquid, we have followed the line initiated by de Gennes, using a Molecular Stress Function model of the Doi and Edwa...
متن کاملTheory of fishnet negative-index optical metamaterials.
We theoretically study fishnet metamaterials at optical frequencies. In contrast with earlier works, we provide a microscopic description by tracking the transversal and longitudinal flows of energy through the fishnet mesh composed of intersecting subwavelength plasmonic waveguides. The analysis is supported by a semianalytical model based on surface-plasmon coupled-mode equations, which provi...
متن کاملHigh-quality AlN epitaxy on nano-patterned sapphire substrates prepared by nano-imprint lithography
We report epitaxial growth of AlN films with atomically flat surface on nano-patterned sapphire substrates (NPSS) prepared by nano-imprint lithography. The crystalline quality can be greatly improved by using the optimized 1-μm-period NPSS. The X-ray diffraction ω-scan full width at half maximum values for (0002) and (102) reflections are 171 and 205 arcsec, respectively. The optimized NPSS con...
متن کاملFilling of nano-via holes by laser-assisted direct imprint
A new technique for filling narrow and high-aspect ratio nanoscale via holes by laser-assisted direct imprint has been proposed and developed. In the process, the filling material (e.g., metals or Si) is first deposited onto the nano-via holes by a deposition method that has a poor step coverage and hence fills the holes partially with voids. Then a mirror-flat transparent plate (mold) is press...
