Sims secondary ion

WebbAbstract. Secondary ion mass spectrometry (SIMS) is a desorption mass spectrometry (MS) technique, and is widely used in industry and research. SIMS can be employed to obtain high-resolution 2-D and 3-D mass spectrometric images, and accurate atomic and molecular distributions as a function of depth in samples (‘depth profiles’).

Webb28 aug. 2024 · Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is used for chemical analysis of surfaces. ToF-SIMS is a powerful tool for polymer science because it detects a broad mass range with good mass resolution, thereby distinguishing between polymers that have similar elemental compositions and/or the same types of functional …

WebbSecondary Ion Yields The SIMS ionization efficiency is called ion yield, defined as the fraction of sputtered atoms that become ionized. Ion yields vary over many orders of magnitude for the various elements. The most obvious influences on ion yield are ionization potential for positive ions and electron affinity for negative ions. 8 WebbSecondary ion mass spectrometry(SIMS) is used to analyze solid surfaces and thin filmsby sputteringthe surface with a focused primary ion beamand collecting and analyzing ejected secondary ions. There are many different sources for a primary ion beam. However, the primary ion beam must contain ions that are at the higher end of the energy scale.
