This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The crystallographic orientation of a metal affects its surface energy and structure, and has profound implications for surface chemical reactions and interface engineering, which are important in areas ranging from optoelectronic device fabrication to catalysis. However, it can be very difficult and expensive to manufacture, orient, and cut single crystal metals along different crystallographic orientations, especially in the case of precious metals. One approach is to grow thin metal films epitaxially on dielectric substrates. In this work, we report on growth of Pt and Au films on MgO single crystal substrates of (100) and (110) surface orientation for use as epitaxial templates for thin film photovoltaic devices. We develop bias-assisted sputtering for deposition of oriented Pt and Au films with sub-nanometer roughness. We show that biasing the substrate decreases the substrate temperature necessary to achieve epitaxial orientation, with temperature reduction from 600 to 350 °C for Au, and from 750 to 550 °C for Pt, without use of transition metal seed layers. Additionally, this temperature can be further reduced by reducing the growth rate. Biased deposition with varying substrate bias power and working pressure also enables control of the film morphology and surface roughness.

Available in PDF, EPUB and Kindle. Book excerpt: This selection is focused on coatings and films with applications in optoelectronics, such as photovoltaics, photocatalysis, and light-based sensors and phenomena. The studies investigate the optimal composition, crystalline structure, and morphology to deliver the different functionalities sought. Obtaining transparent p-type electrodes is challenging but extremely relevant in optoelectronics. Electric conduction mechanisms and the correlations with structure and doping are discussed. The important issue of the degradation pathways in perovskite-based solar cells and the possibilities offered by different types of coatings to encapsulate the devices as well as the beneficial effect of silica coating as an antireflection and antisoiling layer on well-established solar cells are discussed. New designs of nanoplasmonic films for chemical and biological molecule sensing are reviewed, such as the combination of metallic nanoparticles and nanostructured semiconductors and dispersing metallic or bi-metallic nanoparticles in CuO films. The impacts of structure, defects, and morphology on the photoactivated properties of WO3 films and on the shape memory behavior in Cu–Al–Ni thin films are discussed. Aggregated TiO2 nanoparticles on TiO2 layers are shown to enhance optical transmittance and confer a superhydrophilic characteristic. Finally, aspects of the fundamental characterization of thin films, Drude damping in thin films, and laser-induced deflection technique are discussed.
