Organic SIMS with single massive gold projectile: Ion yield enhancement by silver metallization Conference Paper

abstract

• The yield of CN from glycine rises from one CN per projectile impact to two when the sample is covered with a nominally 1 nm thick layer of silver. These yields were obtained for bombardment with Au 4004+ projectile with 136 keV impact energy. A multitude of CN-based clusters, e.g. Ag x O y (CN) z are produced concurrently. As a result, a total of three CN-based secondary ions are generated per projectile impact. The exceptionally high yield for CN is of interest for biological SIMS. 2006 Elsevier B.V.
