What is Angle Resolved Photoemission Spectroscopy (ARPES)?
Angle Resolved Photoemission Spectroscopy (ARPES) is a powerful experimental technique used to study the electronic structure of materials. By measuring the kinetic energy and emission angle of electrons ejected from a sample upon exposure to ultraviolet or X-ray photons, ARPES provides detailed information about the energy and momentum of the electrons within the material. This data is crucial for understanding the electronic properties and behaviors of various materials, making it invaluable in the field of catalysis.
