[AES] Auger Electron Spectroscopy

By measuring the kinetic energy distribution of Auger electrons emitted by electron beam irradiation, insights can be gained regarding the types and quantities of elements present on the sample surface.

- Qualitative and quantitative analysis of solid material surfaces (depth of several nm) is possible. - Qualitative and quantitative analysis of micro-regions (approximately tens of nm to sub-micron) is possible. - Depth profile analysis, line analysis, and area analysis of major component elements can be measured. - For several elements such as Si and Al, evaluation in both oxide and metallic states is possible. - Identification of specific areas of interest using SEM images is possible.
