(2017-05-09)The purpose of this study was to explore the performance of a secondary ion mass spectrometry (SIMS) technique for probing nanovolumes. The variant of SIMS used involves bombardment with individual massive projectiles ...
-
(2014-07-31)Secondary ion mass spectrometry (SIMS) with a massive cluster projectile and run in the event-by-event bombardment/detection mode has been applied to perform nanoscale analysis. Massive clusters, specifically Au_(400)^(4+), ...
-
(2009-05-15)Cluster secondary ion mass spectrometry (SIMS) analyses of layer-by-layer thin films were performed to investigate the depth/volume of SI emission and accuracy of the SI signal. The thin-layered samples were assembled by ...

(2012-08-16)Impacts of high kinetic energy massive gold clusters (~ 500 keV Au400+4) exhibit significantly enhanced secondary ion yields relative to traditional atomic or polyatomic primary ions (e.g. Au3 and C60). The one-of-a-kind ...
-
A distinct feature of secondary ion mass spectrometry, SMIS, with large projectiles, e.g. C60, Au400, Ar2000, is abundant secondary ion, SI, emission. Thus it is feasible to run experiments in the event-by-event bombardment ...

(Texas A&M University, 2007-09-17)Secondary ion mass spectrometry, SIMS, is one of the most versatile surface analytical techniques. The significant parameter determining the performance of SIMS is the secondary ion yield. Atomic projectiles, traditionally ...
-
(Texas A&M University, 2004-09-30)Some collision cascades, induced by keV polyatomic projectiles, result in the emission of multiple secondary ions. Such co-emissions imply that the ejecta originate from molecules co-located within the nano-volume perturbed ...
