This book was released on 2012 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: We identified that the growth parameters are vital to control the crystallinity, morphology and the defect levels in the synthesized ZnO nanowires. SEM, XRD, TEM, HRTEM analysis show that the nanostructures are highly crystalline and are vertically oriented. We also report the in-situ growth of PbS nanoparticles without linker on the surface of well -oriented ZnO NWs by (SILAR) technique. The PbS Nanoparticles are packed tightly on the surface of the ZnO Nanowires with different sizes and densities, without insulating nature organic ligands, which might affect both the electronic structure at the interface and the electron - transfer rate. The SEM, TEM, HRTEM, PL and XRD analysis, confirm the attachment of the spherical shape polycrystalline PbS nanoparticles. We propose at the end of the thesis the p-PbS /n-ZnO hetero-junction with its future applications in solar cells.

This book was released on 2012-08 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fabrication of efficient Ultraviolet Light Emitting Diodes (UV LEDs) is a challenging task for the semiconductor industry of the modern times. Finding the suitable semiconducting material is the key in order to make efficient LEDs. This book aims at understanding the use of ZnO in UV LEDs that demands the understanding of its optical properties first. Structural and optical properties of any semiconducting material are strongly correlated. An adequate knowledge and understanding of this relationship is necessary for fabrication of devices with desired optical properties. The aim of this work was to investigate the change in optical properties caused by growth techniques and substrate modification. To study the influence of growth technique on optical properties, ZnO nanostructures were grown using atmospheric pressure metal organic chemical vapor deposition (APMOCVD) and chemical bath deposition (CBD) techniques. Off-cut angle of SiC substrates were modified to observe the change on the optical properties. The results that are obtained demonstrate a significant contribution in the fields of ZnO based nano-optoelectronics and nano-electronics.

This book was released on 2021-04-08 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent rapid development of electronics and electro-optical devices demands affordable and reliable materials with enhanced performance. Forming nanocomposites of already well-known materials is one possible route towards novel functional materials with desirable synergistic enhanced properties. Incompatible chemical properties, mismatched crystal structures and weak bonding interactions between the substances, however, often limit the number of possible nanocomposites. Moreover, using an inexpensive, facile, large-area and flexible fabrication technique is crucial to employ the new composites in industrially viable applications. This thesis focuses on the synthesis and characterization of different zinc oxide/graphene (ZnO/GR) nanocomposites, well suited for optoelectronics and photocatalysis applications. Two different approaches of i) substrate-free random synthesis, and ii) template-assisted selective area synthesis were studied in detail. In the first approach, ZnO nanoparticles/rods were grown on GR. The obtained nanocomposites were investigated for better GR dispersity, electrical conductivity and optical properties. Besides, by adding silver iodide to the nanocomposite, an enhanced plasmonic solar-driven photocatalyst was synthesized and analyzed. In the second approach, arrays of single, vertically aligned ZnO nanorods were synthesized using a colloidal lithography-patterned sol-gel ZnO seed layer. Our demonstrated nanofabrication technique with simple, substrate independent, and large wafer-scale area compatibility improved the alignment and surface density of ZnO nanorods over large selective growth areas. Eventually, we found a novel method to further enhance the vertical alignment of the ZnO nanorods by introducing a GR buffer layer between the Si substrate and the ZnO seed layer, together with the mentioned patterning technique. The synthesized nanocomposites were analyzed using a large variety of experimental techniques including electron microscopy, photoelectron spectroscopy, x-ray diffraction, photoluminescence and cathodoluminescence spectroscopy for in-depth studies of their morphology, chemical and optical properties. Our findings show that the designed ZnO/GR nanocomposites with vertically aligned ZnO nanorods of high crystalline quality, synthesized with the developed low-cost nanofabrication technique, can lead to novel devices offering higher performance at a significantly lower fabrication cost.

Available in PDF, EPUB and Kindle. Book excerpt: Zinc Oxide nanostructures are important for many applications, specifically for developing novel catalysts and sensors which our research group has been working on. The objectives of this thesis are: (1) synthesis and characterization of complex ZnO nanostructures; (2) development of synthesis protocols for high-yield and reliable synthesis of nanostructures. In this thesis, chapter 1 introduces the background of nanoscience and nanotechnology, with a focus on nanomaterials. In chapter 2, the fundamental knowledge of ZnO and relevant characterization techniques are introduced, specifically the crystallography of ZnO wurtzite structure and the scanning (transmission) electron microscopy. Several goals have been achieved and they are reported in chapter 3 and 4. First, the nano-pyramid decorated microwires were fabricated. A growth mechanism for those complex nanostructures was proposed. Second, surface modification such as grooved surfaces of ZnO nanostructures has been realized. Grooved nanowires, microbelts, and micrometer-scale tetra-pods are discussed. Third, the effects of oxygen partial pressure on the growth of ZnO have been investigated. All the ZnO nanostructures reported in this thesis were synthesized by a physical vapor deposition method. The field-emission scanning electron microscope was used to examine the morphologies of the synthesized nanostructures. Aberration-corrected scanning transmission electron microscopy provided information on the fabricated nanostructures.
