Fabrication And Characterization

Indefinite optical properties, which are typically characterized by hyperbolic dispersion relations, have not been observed in naturally occurring materials, but can be realized through a metamaterial approach. We present here the design, fabrication and characterization of nanowire metamaterials with indefinite permittivity, in which all-angle negative refraction of light is observed. The bottom-up fabrication technique, which applies electrochemical plating of nanowires in porous alumina template, is developed and demonstrated in achieving uniform hyperbolic optical properties at a large scale. We developed techniques to improve the uniformity and to reduce the defect density in the sample. The non-magnetic design and the off-resonance operation of the nanowire metamaterials significantly reduce the energy loss of electromagnetic waves and make the broad-band negative refraction of light possible.

Template Wetting

Piezoelectric nanotubes are applicable to many areas including sensors, actuators, and energy storage. Before these applications can be realized using nanoscale components, a study is needed to characterize the piezoelectric-properties of nanotube geometries versus the piezoelectric-properties of a thin-film of the same material (not shown here). The material used in this study is (PZT) lead-zirconate-titanate, PbZr0.5Ti0.48O3. In this work, 200nm diameter PZT structures are manufactured by a template wetting procedure. These ceramic nanotubes are brittle but hold up well inside the alumina template structure. Having an array of nanometer-sized piezoelectric-tubes has been hypothesized to give comparable results to that of thin-films of the same material. The research described in this paper is a preliminary step towards testing this hypothesis via characterization and later producing piezoelectric-nanoscale-sensors, which are both small and efficient.
