Photoemission spectroscopy (PES) is an analytical technique used to investigate the electronic properties of materials. It involves the absorption of photons (light) by a sample, which results in the emission of electrons. The primary goal of PES is to study the energy and distribution of these emitted electrons, providing valuable insights into the material's electronic structure. ### Basic Principles: - **Excitation:** A sample is irradiated with high-energy photons, typically from ultraviolet or X-ray sources.
