Traditional materials for thermoelectric such as bismuth telluride have been studied and utilized commercially for the last half century, but recent advancements in materials selection are one of the principal function of the active thermoelectric device as it determines the reliability of the fabrication regarding technical and economic aspects. Recently, many researcher's efforts have been made to utilize oxide nanomaterials for wearable thermoelectric power generator (WTPG) applications which may provide environmental stable, mechanical flexibility, and light weight with low cost of manufacturing. In precise, fabric containing oxide metals have shown great promise as P−/N-type materials with improved transport and UV shielding properties. On the other hand, we have focused on ZnO nanostructures as a high-efficiency WTPG material because they are non-toxic to skin, inexpensive and easy to obtain and possess attractive electronic properties, which means that they are available for clothing with low-cost fabrication. To our observation, we are chaptering about the thermoelectric properties of ZnO and their composite nanostructures coated cotton fabric via the solvothermal method for the first time.

Abstract: Abstract of thesis entitled FABRICATION AND CHARACTERIZATION OF ZINC OXIDE (ZnO) NANOSTRUCTURES Submitted by Leung Yu Hang For the degree of Master of Philosophy at The University of Hong Kong in January 2006 Since the discovery of carbon nanotubes by Iijima in 1991, increasing research effort has been devoted to the synthesis and characterization of nanostructured materials. Materials at this scale exhibit novel properties which cannot be found in their bulk form. In silicon nanowires, for example, the bandgap of Si nanowires increases from 1.1 eV to 3.7 eV when the nanowire diameter decreases from 7 nm to 1.3 nm. In recent years, nanostructures of various semiconductors like Si, gallium arsenide, gallium nitride, and zinc oxide have been demonstrated. Among them, ZnO has been recognized as a promising material for a variety of applications in the field of photonics, optoelectronics, gas sensing, field emission, and piezoelectrics. To realize the incorporation of ZnO nanostructures into real life applications, lots of work need to be done, including synthesis of the nanostructures, and understanding of their properties. In this study, a number of ZnO nanostructures (tetrapods, nanorods, nanoribbons/combs, multipods) were fabricated by thermal evaporation and hydrothermal synthesis methods. The morphologies and, structural and optical properties of the resultant nanostructures were then characterized by various techniques, such as scanning electron microscopy, transmission electron microscopy, selected area electron diffraction, energy dispersive X-ray spectroscopy, X-ray diffractometry, photoluminescence and electron paramagnetic resonance. It was observed that fabrication conditions could significantly affect the properties of the nanostructures. All nanostructures exhibited one UV peak and one broad peak in the visible spectrum. The major difference is that the nanostructures fabricated by thermal evaporation exhibited green PL emission while the nanorods synthesized by hydrothermal method gave yellow emission. Green emission was observed even without the presence of the EPR signal at g 1.96 in some samples. This result contradicts the commonly cited oxygen vacancy hypothesis of green emission of ZnO. Obviously, that hypothesis does not apply to all ZnO samples. The nanorod sample with yellow emission also exhibited strong EPR signal similar to the green emitting sample. A possible explanation for the obtained results is that there are two different deep levels responsible for the green and yellow emission respectively. Stimulated UV emission of three different nanostructures (tetrapods, nanoribbons/combs, and nanorods) was studied by time-resolved photoluminescence (TRPL). It was observed that different nanostructures exhibited different lasing thresholds, emission delay times and decay times. The difference in the lasing behaviors of the nanostructures is likely due to the difference in morphology, mode of cavity, or even native defects present in the material.

Dye Sensitized Solar Cells are an original alternative to conventional photovoltaic devices. With efficiencies up to 12% and low production costs, it is now a serious technology for mass market production. Development of new deposition techniques and original morphologies for the anode, which is a key component of the device, is expected to make this technology more competitive. In this work, we have used electrodeposition to prepare and characterize Zinc Oxide nanostructures. This technique is very suitable for preparation of nanostructured material with controlled morphology at nanoscale and very low cost of production. After introducing the context of Dye-Sensitized Solar cells with the most advanced results and the current reflections on the physical aspects of these devices, we have prepared a variety of promising nanostructures. Nanoporous ZnO layers have been adapted for deposition on ZnO-Al as substrate and a highly organized structure could be obtained. Hierarchical structures composed of highly conductive nanowires and nanoporous structure with high surface area have been synthesized. Electrochemical Impedance Spectroscopy has been carried out to characterize these nanostructures in order to investigate both optoelectronic and geometrical aspects. In a third part, ZnO-based DSSC have been prepared. The performance of the nanostructured ZnO layers and the influence of the substrate used for deposition have been investigated. Photovoltaic conversion efficiency up to 5.2% could be obtained in the optimized conditions.

Nanostructured Anodic Metal Oxides: Synthesis and Applications reviews the current status of fabrication strategies that have been successfully developed to generate nanoporous, nanotubular and nanofibrous anodic oxides on a range of metals. The most recent achievements and innovative strategies for the synthesis of nanoporous aluminum oxide and nanotubular titanium oxide are discussed. However, a special emphasis is placed on the possibility of fabrication of nanostructured oxide layers with different morphologies on other metals, including aluminum titanium, tantalum, tin, zinc, zirconium and copper. In addition, emerging biomedical applications of synthesized materials are discussed in detail. During the past decade, great progress has been made both in the preparation and characterization of various nanomaterials and their functional applications. The anodization of metals has proven to be reliable for the synthesis of nanoporous, nanotubular and nanofibrous metal oxides to produce a desired diameter, density, aspect ratio (length to diameter) of pores/tubes, and internal pore/tube structure.
