What Does AEY Stand For?

AEY stands for Auger Electron Yield

Auger Electron Yield (AEY) is a measure of the efficiency of the Auger electron emission process, where an incident electron interacts with atoms to result in the ejection of Auger electrons. It quantifies the number of Auger electrons emitted per incident electron and is crucial in characterizing surface and material properties, as well as in applications such as surface analysis and thin film research. AEY provides insight into electronic structure, chemical composition, and the dynamics of interactions at the atomic level.
