• Brief description:Angle-Resolved Photoemission Spectroscopy is an experimental technique used to investigate the electronic band structure of solids. Based on the Photoelectric Effect, ARPES measures the kinetic energy and emission angle of photoemitted electrons, enabling direct determination of the energy–momentum relationship of electronic states in crystalline materials.
