Question
Chapter 21, Problem 21.8QAP
Interpretation Introduction
Interpretation:
The instrumental difference between static SIMS and dynamic SIMS, the difference between information obtained from static SIMS and information obtained from dynamic SIMS, the imaging SIMS and types of information obtained with imaging SIMS should be determined.
Concept introduction:
Secondary ion mass spectroscopy (SIMS) is used to maintain the integrity of the surface by using static or dynamic condition in the time scale duration of the experiment.
