Thin films

Thin films are extremely thin layers of material, often just a few atoms to a few micrometers thick. They are used in a variety of applications, such as coatings on lenses, solar cells, and electronic devices. The unique properties of thin films arise from their small thickness and the way light interacts with them, leading to phenomena like interference and reflection. This science helps improve efficiency in technology and enhance the performance of everyday products, making them an important area of research and innovation in engineering and materials science.
