Book excerpt: Nanostructured Thin Films: Fundamentals and Applications presents an overview of the synthesis and characterization of thin films and their nanocomposites. Both vapor phase and liquid phase approaches are discussed, along with the methods that are sufficiently attractive for large-scale production. Examples of applications in clean energy, sensors, biomedicine, anticorrosion and surface modification are also included. As the applications of thin films in nanomedicine, cell phones, solar cell-powered devices, and in the protection of structural materials continues to grow, this book presents an important research reference for anyone seeking an informed overview on their structure and applications. - Shows how thin films are being used to create more efficient devices in the fields of medicine and energy harvesting - Discusses how to alter the design of nanostructured thin films by vapor phase and liquid phase methods - Explores how modifying the structure of thin films for specific applications enhances their performance
