What is Ultraviolet Photoelectron Spectroscopy (UPS)?
Ultraviolet Photoelectron Spectroscopy (UPS) is an analytical technique used to study the electronic structure of materials. It involves the emission of photoelectrons from a material's surface when it is irradiated with ultraviolet (UV) light. By measuring the kinetic energy of these emitted electrons, researchers can obtain valuable information about the material's electronic states, work function, and density of states.
