Field desorption

{{DefName| 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. }}
