When an electron is ejected from a metal surface it has kinetic energy. The amount of kinetic energy the electron has depends on the difference between the energy of the photon and the work ...

XPS relies on the photoelectric effect, where irradiating a material with X-rays causes the emission of core electrons. The kinetic energy of these emitted electrons is measured, which can be directly ...

a phenomenon known as the photoelectric effect. By analyzing the emitted electron and its kinetic energy, valuable insights can be gained into the irradiated atom. This principle underlies ...
