Explore: Electron Impact Ionization

Electron ionization (EI, formerly known as electron impact ionization and electron bombardment ionization) is an ionization method in which energetic

Impact ionization is the process in a material by which one energetic charge carrier can lose energy by the creation of other charge carriers. For example

solution for the ionization rate is possible. Tunnel ionization is ionization due to quantum tunneling. In classical ionization, an electron must have enough

provide an ion supply (by surface ionization or electron impact ionization in a plasma) to neutralize the electron space charge. From a physical electronic

Penning ionization is a form of chemi-ionization, an ionization process involving reactions between neutral atoms or molecules. The Penning effect is
