What Does ARPES Stand For?

ARPES stands for Angle Resolved Photoelectron Spectroscopy

ARPES, or Angle Resolved Photoelectron Spectroscopy, is a sophisticated experimental technique used to investigate the electronic structure of materials. By measuring the momentum and energy of photoelectrons ejected from a sample when illuminated by ultraviolet or X-ray photons, ARPES provides detailed information about the band structure, surface states, and electron dynamics in solids. This valuable information is crucial for understanding the physical properties of materials, enabling advancements in fields such as condensed matter physics, materials science, and nanotechnology.
