Orange Book Entry
This term is used to describe the formation of ions in the gas phase from a material deposited on a solid surface (known as an ????????????????????????emitter??????????????????????) in the presence of an electric field. As this process probably encompasses ionization by field ionization as well as other mechanisms of ionization the term ????????????????????????field desorption?????????????????????? is not a precise one, despite its widespread acceptance.
