Recent advances in science and technology have led researchers to develop both flexible and transparent conductors using various nanomaterials including metals, carbon-based materials, and conducting polymers. Those nanomaterials provide unique mechanical, thermal, electrical and optical properties, but are typically restricted to a single physical domain. Only by using a systemic approach different functionalities across multiple domains can be simultaneously achieved and engineered.

520 $a Recent advances in science and technology have led researchers to develop both flexible and transparent conductors using various nanomaterials including metals, carbon-based materials, and conducting polymers. Those nanomaterials provide unique mechanical, thermal, electrical and optical properties, but are typically restricted to a single physical domain. Only by using a systemic approach different functionalities across multiple domains can be simultaneously achieved and engineered.
520 $a In this dissertation, I demonstrate a comprehensive study on design, fabrication, and characterization of transparent flexible nanostructures using metal materials. Such a structure and material-based approach be an attractive solution due to their excellent structural stability as well as superb electrical and thermal conductivity. Firstly, I present an approach fabricate and control novel complex platinum nanostructures with accordion-like profile on silicon substrate using atomic layer deposition (ALD) and interference lithography. A polymer template with one-dimensional periodic grating profile is prepared as a sacrificial layer for thin conformal platinum film on top, and removed by thermal process. During this template removal process, a unique structural transformation of the nanostructure profile is occurred and a geometric model is suggested to anticipate the final profiles of metal layer. Using different duty cycles and aspect ratios of polymer template, I present a wide variety of cross-sectional profiles from wavy geometry to pipe array patterns, and electrical characterization of those profiles is performed.
520 $a Secondly, as an alternative method to have conformal metal film on nanostructured polymer surfaces, I introduce an approach using conventional physical vapor deposition (PVD). To enhance the step coverage of metal PVD, a thin metal oxide interlayer by ALD is presented. The improvement on conformality and morphology of the metal layer is analyzed using scanning electron microscopy, transmission electron microscopy, energy-dispersive x-ray spectroscopy, and electrical conductivity measurement. Gold thermal evaporation on complex polymer templates using different aspect ratios and deposition speeds is mainly tested, and three different metal oxide layers, which are aluminum oxide, zinc oxide, and titanium dioxide, are examined as adhesive interlayers for better conformal metal coating by PVD technique.
520 $a Finally, after completing the steps for fabricating metallic nano-accordion structures on silicon substrate by ALD or conformal PVD, a follow-up process to overcome the limited optical transmission of metallic structures and to transfer the nanostructures onto elastomeric substrate are discussed. By a secondary patterning of metal layer, physical openings on metal layer are created and then, the optical transmittance of microstructured metallic nano-accordions is examined. After transfer step of metallic nano-accordions to soft substrate, the stretchability of the novel metallic nano-accordion structures is tested using a tensile module to confirm the mechanical flexibility. The proposed metallic nanostructures can find their applications not only in flexible or stretchable electronics, but also potentially in photonics and nanofluidics.
