Applications of Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS)

WebThe early‐stage spectrometer is operated in a mode of dynamic SIMS (DSIMS). The DSIMS directs a high flux of primary ion to the sample surface, eroding the surface rapidly. Therefore, DSISM is not suitable for ultra‐thin surface analysis. A static SIMS (SSIMS) was developed in 1970’s. WebDec 15, 2008 · It is a significant SIMS attribute that matrix and impurity species can be monitored and quantified in the same profile. Quantification has been established for impurity and matrix species in a number of materials such as Si x Ge (1 − x), Al (x) Ga (1 − x) As, and Al x Ga (1 − x) N [17], [18], [19].The results for AlGaN are of particular interest …
