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.

Lithography Technique

This paper compares two laser-assisted processes developed by the authors for the fabrication of microwave devices based on nanowire arrays loaded inside porous alumina templates. Pros and cons of each process are discussed in terms of accuracy, reproducibility and ease of fabrication. A comparison with lithography technique is also provided. The efficiency of the laser-assisted process is demonstrated through the realization of substrate integrated waveguide (SIW) based devices. A Nanowired SIW line is firstly presented. It operates between 8.5 and 17 GHz, corresponding to the first and second cut-off frequency of the waveguide, respectively. Next, a Nanowired SIW isolator is demonstrated. It shows a nonreciprocal isolation of 12 dB (corresponding to 4.4 dB/cm), observed in absence of a DC magnetic field, and achieved through an adequate positioning of ferromagnetic nanowires inside the waveguide cavity.
