Time-of-flight secondary ion mass spectrometry (ToF-SIMS) enables very high-resolution chemical analysis of solid surfaces. It is used to detect molecular fragments characteristic of PAMs and to map
For D-SIMS, a high-dose primary ion beam is used to sputter material from the sample surface. This high-dose beam thoroughly damages the sample surface, destroying all chemical
This paper demonstrates how secondary electron energy spectroscopy (SEES) performed inside a scanning electron microscope (SEM) can be used to map sample atomic number
This chapter will discuss the Secondary Ion Mass Spectrometry (SIMS) technique for the new SIMS user, illustrating how SIMS fits in with other common surface analytical techniques. It will
The trajectories taken by secondary ions in the mass spectrometer are controlled by their velocity v, (kinetic energy E K), and the angle at which they emerge from the sample.
By mass analysis of the ejected secondary ions information on the composition of the material as a function of depth can be gained (Secondary Ion Mass Spectrometry, SIMS). The positive as well as
Secondary ions are collected and detected by a mass spectrometer. If the primary ion beam is focused and scanned across the surface, the resulting mass-to-charge ratio (m/z) signals can be...

Secondary-ion mass spectrometry (SIMS) is a technique used to analyze the composition of solid surfaces and thin films by sputtering the surface of the specimen with a focused primary ion beam and collecting and analyzing ejected secondary ions. The mass/charge ratios of these secondary ions are measured with a mass spectrometer to determine the elemental, isotopic, or molecular composition of the su
Benchtop NMR spectrometers represent a very powerful alternative at a fraction of the cost and laboratory footprint. However, concerns about resolution and managing second-order
This study investigates the effect of hot workability parameters such as temperature, strain rate, and overall strain on the microstructure evolution.
