High Spatial Resolution Time-of-Flight Secondary Ion Mass Spectrometry for the Masses: A Novel Orthogonal ToF FIB-SIMS Instrument with In Situ AFM
Figure 11
Enlargement of part of the profile from Figure 9 showing a superimposed fit of a complementary error function and the 20% and 80% points. The inferred spot size for the FIB beam (and so the spatial resolution of the SIMS signal) is between 40 and 50 nm for this dataset.
