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.

In this study, vertically aligned CuInS2nanorod arrays were successfully fabricated by sulfurization method with porous alumina template, which was used to prepare CuInS2thin film in the reported paper. The nanorod arrays showed the diameters of about 200nm and the length of about 1μm, and highly vertically aligned on the CuInS2thin film, were characterized by scanning electron microscope. The sample was identified as the single chalcopyrite phase and the crystal structure with (112), (200)/(004), (202)/(204) and (116)/(312) atomic planes orientation by Raman scattering and X-ray diffraction, respectively. The Cu: In: S atomic ratio of 1:0.84:1.94 was exhibited in the sample by energy dispersive X-ray spectroscopy.
