Photoelectrons are emitted from a metallic material when it absorbs light radiation. The process was discovered by Heinrich Hertz and later explained by Albert Einstein. Photoelectron spectroscopy is used to study the surface region of a sample material, with X-ray spectroscopy and ultraviolet photoelectron spectroscopy being the two basic types. The latest synchrotron equipment allows […]
Photoelectron spectroscopy analyzes substances by ejecting electrons with photons of known wavelengths. Ionization energy depends on the charge on the nucleus and orbital of the electron. X-ray photoelectron spectroscopy is used for solid samples, while ultraviolet photoelectron spectroscopy is used for electronic structure analysis. Photoelectron spectroscopy is a method of analyzing substances using the photoelectric […]
