CPC classification number: H01J27/26
Abstract: This invention relates to a liquid metal ion source which melts a source material and extracts ions. Stable extraction of ions of at least one element selected from among As, P and B for a long period of time can be attained by using as a source material an alloy having a composition represented by the formula L.sub.X R.sub.Y M.sub.A wherein X, Y and A each stands for atomic percentage; L at least one element selected from among Pt, Pd and Ag; R at least one element selected from among As, P and B; M at least one element selected from among Ge, Si and Sb; 5

Abstract: An ionic liquid ion source can include a microfabricated body including a base and a tip. The body can be formed of a porous material compatible with at least one of an ionic liquid or room-temperature molten salt. The body can have a pore size gradient that decreases from the base of the body to the tip of the body, such that the at least one of an ionic liquid or room-temperature molten salt is capable of being transported through capillarity from the base to the tip.
