Web26 mei 2015 · In TOF-SIMS two prominent ion beam focusing modes have been described. 23-25 The so-called Burst Alignment (BA) is a mode which produces a very narrow beam diameter, well below one micron, using a pair of electrostatic lenses. WebTime-of-flight secondary ion mass spectrometry (TOF-SIMS) was performed with an ION-TOF TOF-SIMS 5 to create a depth profile of the composition of our layers. A pulsed 15keV-69Gaþ ion beam scanning a (50 50)mm2 area was used for analysing the sample. Depth profiling was done using a pulsed 1.0keV-Csþ beam covering an area of (300 …
