This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Copper oxides, including cuprous oxide and cupric oxide, are prepared by electrochemical deposition. The structural, optical and electrical properties of as-deposited copper oxides are evaluated, based on which cuprous oxide is selected as a promising material for photovoltaic applications. Electrodeposited cuprous oxide is a p-type semiconductor with a direct band gap of 2.06 eV. The mechanism of how pH affects the structural and electrical properties of electrodeposited cuprous oxide films is studied. In the pH range of 7.5 to 12.0, there are three different preferred crystal orientations: (100), (110) and (111). With different orientations, cuprous oxide shows different surface morphology and grain size. Bath pH effect on structural properties is explained by its effect on the growth rate of different crystallographic planes with different Cu+/O2- ratios. Capacitance-voltage measurements are performed to study electrical properties of differently oriented cuprous oxide films. The results show that the flat band potential shifts negatively as the bath pH increases. Electrodeposited cupric oxide is a p-type cupric oxide with an indirect band gap of 1.32 eV. Different cleaning methods are used to clean the substrate surface for electrodeposition of cupric oxide. Electrochemical etching is proven to be an effective method for Cu substrate cleaning in cupric oxide deposition. In particular, in-situ electrochemical etching is developed, which prevents the cleaned substrate from exposure to air. Current-voltage characterization shows that cupric oxide deposited on electrochemically etched Cu substrates has favorable electrical properties and better rectification behavior. Cuprous oxide is selected for the fabrication of p-n homo-junction because it has better crystallinity, bigger grains, better control over crystal quality and a direct band gap. Based on the model that bath pH can control the stoichiometry and native point defects in electrodeposited cuprous oxide films, both p-type and n-type cuprous oxides are successfully deposited at different bath pH values. For samples deposited at pH below 7.5, cuprous oxides are n-type semiconductors, while at bath pH above 9.0, cuprous oxides are p-type semiconductors. Furthermore, a two-step deposition process is developed to fabricate a p-n homo-junction in cuprous oxide. Current-voltage measurements show a typical rectification behavior of a p-n junction for these samples, which suggest that a p-n homo-junction of cuprous oxide is achieved, which is, to our knowledge, the first p-n homo-junction of cuprous oxide prepared by any method. The significance of this invention is because it enables the fabrication of solar cell with a reasonable high conversion efficiency (& sim;10%) at a very low cost.

Book excerpt: Metal Oxides for Next Generation Optoelectronic, Photonic and Photovoltaic Applications focuses on the optoelectronic, photonic and photovoltaic behaviors of metallic oxides and closely related phenomena, from elementary principles to the latest findings. Each chapter includes a comprehensive evaluation of the synthesis and characterization of the most relevant metal oxides nanostructures for each application. In addition, there is a focus on methods to tune the materials’ properties in order to improve devices performance. This book is suitable for researchers and practitioners in academia and industry working in the disciplines of materials science and engineering, chemistry and physics. Metal oxides are widely used in various optoelectronic devices, photonics, display devices, smart windows, sensors, optical components, energy-saving, and harvesting devices. Each application requires materials with their own specific properties. By controlling the particle size, shape, crystal structure, one can tune various properties of metal oxides viz. bandgap, absorption properties, conductivity, which alter the material for the specific application. Includes discussions of synthesis and characterization of metal oxides materials for applications in next-generation optoelectronic, photonic and photovoltaic devices Emphasizes material design strategies of metal oxide nanostructures Focuses on the optoelectronic, photonic and photovoltaic behaviors of metallic oxides and closely related phenomena, from elementary principles to the latest findings

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the important physical phenomenon of Surface Plasmon Resonance or Surface Plasmon Polaritons in thin metal films, a phenomenon which is exploited in the design of a large variety of physico-chemical optical sensors. In this treatment, crucial materials aspects for design and optimization of SPR sensors are investigated and outlined in detail. The text covers the selection of nanometer thin metal films, ranging from free-electron to the platinum type conductors, along with their combination with a large variety of dielectric substrate materials, and associated individual layer and opto-geometric arrangements. Furthermore, as-yet hardly explored SPR features of selected metal–metal and metal–dielectric super lattices are included in this report. An in-depth multilayer Fresnel evaluation provides the mathematical tool for this optical analysis, which otherwise relies solely on experimentally determined electro-optical materials parameters.
