Two-photon photoelectron spectroscopy (TPPE) is a sophisticated technique used in the field of surface science and condensed matter physics to investigate the electronic properties of materials. This technique enables the study of the electronic structure and dynamics of materials at various interfaces, such as solid-vacuum, solid-liquid, or solid-gas interfaces.
