Photoemission spectroscopy (PES), also known as photoelectron spectroscopy, refers to energy measurement of electrons emitted from solids, gases or liquids by the photoelectric effect, in order to determine the binding energies of electrons in the substance. The term refers to various techniques, depending on whether the ionization energy is provided by X-ray, XUV or UV photons. Regardless of the incident photon beam, however, all photoelectron spectroscopy revolves arou… WebCuando la luz brilla en un metal, los electrones pueden ser expulsados de la superficie del metal en un fenómeno conocido como el efecto fotoeléctrico.
