Study Notes
Comparison of AES and XPS
- The main difference between Auger Electron Spectroscopy (AES) and X-ray Photoelectron Spectroscopy (XPS) lies in the excitation source: AES uses a high-energy electron beam, while XPS uses X-ray photons.
Collection Depth in AES
- The typical collection depth in Auger Electron Spectroscopy (AES) is around 0.5-5 nm, making it a surface-sensitive technique.
AES Spectrum
- A representative AES spectrum illustrates the Auger electrons' kinetic energy distribution, which is used to identify the elemental composition of the sample's surface.
