Abstract
Sputter Initiated Resonance Ionization Spectroscopy (SIRIS) is a method allowing a minimum of chemical pretreatment, the chief source of contamination, and providing a highly selective and sensitive measurement of essentially any element. SIRIS is an ultra-sensitive analysis technique which uses an energetic ion beam to sputter a solid sample and Resonance Ionization Spectroscopy (RIS) to selectively and efficiently ionize neutral atoms of the element of interest in the atomized cloud. A primary advantage of SIRIS technology is the potential to reduce or eliminate the matrix effect in direct solids analysis by utilizing the predominant neutral population produced by primary ion bombardment. The principal results reported come from using SIRIS to investigate the spatial distribution of trace elements in specially fabricated crystals or devices.
