This book was released on 2012-03 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiconductor thin films and their junctions such as metal-semiconductor (Schottky barrier) and heterojunctions have received much attention due to their applications in various electronic and optoelectronic devices including solar cells. This book is based on the electrical and optical studies of thin film Schottky barriers and heterojunctions with an aim to use in optoelectronic devices. In this work, two wide band gap semiconductors, one Zinc Selenide (ZnSe) from group II-VI, and another transparent conducting oxide, Indium Tin Oxide are investigated in the forms of thin films and their junctions, for the possible uses as photovoltaic converter. The structural, morphological, optical and electrical (in dark and under illumination) properties of ZnSe and ITO thin films prepared at different growth conditions by thermal evaporation method have been studied by applying different experimental techniques. Schottky barriers and heterojunctions of ZnSe with different barrier metals and semiconductors have been fabricated and their current-voltage and photovoltaic characteristics are studied. The findings of it presented in this book will be helpful for the researchers of this field.

This book was released on 2020-01-03 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyaniline (PANI) is one of the most common and widely studied conducting polymers due to its excellent electro-chemical and electrical properties and its various applications in areas such as solar cell technologies, drug delivery, organic light emitting diodes (OLEDs), field-effect transistors (FETs), sensors, electro-chromic display, etc. PANI thin films play an important role in energy storage and conversion devices and show great potential in the supercapacitors owing to their high specific capacitance, high flexibility, and low cost. However, no in-depth information about this emerging PANI thin film technology is available. Properties, Techniques, and Applications of Polyaniline (PANI) Thin Films: Emerging Research and Opportunities is an essential publication that focuses on high-throughput synthesis of PANI thin films and their characterization techniques. The book also covers promising applications of PANI thin films and applications including solar cells. Featuring research on topics such as solar cells, post-synthesis treatments, and physiochemistry, this book is ideally designed for scientists, industry practitioners, engineers, managers, academicians, researchers, and students seeking coverage in the areas of polymeric applications.

This book was released on 2020-12-10 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have witnessed the flourishing of numerous novel strategies based on the magnetron sputtering technique aimed at the advanced engineering of thin films, such as HiPIMS, combined vacuum processes, the implementation of complex precursor gases or the inclusion of particle guns in the reactor, among others. At the forefront of these approaches, investigations focused on nanostructured coatings appear today as one of the priorities in many scientific and technological communities: The science behind them appears in most of the cases as a "terra incognita", fascinating both the fundamentalist, who imagines new concepts, and the experimenter, who is able to create and study new films with as of yet unprecedented performances. These scientific and technological challenges, along with the existence of numerous scientific issues that have yet to be clarified in classical magnetron sputtering depositions (e.g., process control and stability, nanostructuration mechanisms, connection between film morphology and properties or upscaling procedures from the laboratory to industrial scales) have motivated us to edit a specialized volume containing the state-of-the art that put together these innovative fundamental and applied research topics. These include, but are not limited to: • Nanostructure-related properties; • Atomistic processes during film growth; • Process control, process stability, and in situ diagnostics; • Fundamentals and applications of HiPIMS; • Thin film nanostructuration phenomena; • Tribological, anticorrosion, and mechanical properties; • Combined procedures based on the magnetron sputtering technique; • Industrial applications; • Devices.
