Field ionization is a quantum-mechanical phenomenon that occurs when an atom or molecule is exposed to a high electric field and loses one or more electrons. Electrons can accumulate enough energy under the influence of this powerful field to overcome the binding forces of the atomic nucleus and escape, resulting in the ionization of the atom. This phenomena is very important in high-voltage situations, and it is widely used in mass spectrometry and ionization procedures. Field ionization is used in domains such as analytical chemistry and physics to analyze atomic and molecule structures precisely by producing ions for subsequent investigation. Understanding this process is critical for progress in spectroscopy, microscopy, and other scientific studies.
