Ultraviolet Photoelectron Spectroscopy

Ultraviolet Photoelectron Spectroscopy (UPS) is a technique used to analyze the electronic structure of materials. By shining ultraviolet light on a sample, it ejects electrons from the surface. Measuring these electrons' energies reveals information about the energy levels of the electrons in the material, helping scientists understand properties like chemical composition and how electrons are arranged. It’s a valuable tool in fields like chemistry and material science for studying surfaces and thin films at a detailed electronic level.
