Thin Film

A thin film is a very thin layer of material, often just a few nanometers to micrometers thick. These films can be made from various substances, including metals, semiconductors, or polymers, and are commonly used in technology for coatings, optics, and electronics. For instance, thin films can enhance the properties of surfaces, improve energy efficiency in solar panels, or create anti-reflective coatings on glasses. Their unique properties arise from their small thickness, which can influence how they interact with light and other materials, making them pivotal in modern science and engineering.
