Auger line shape measurements using high resolution positron annihilation induced Auger electron spectroscopy.

摘要

Conventional methods of Auger electron spectroscopy (AES) make use of energetic electron or photon beams to create the core-hole excitations that lead to the Auger transition. The energetic beams result in a large secondary electron background in the Auger peak region. In Positron annihilation induced Auger Electron Spectroscopy (PAES), the core holes are created by matter-antimatter annihilation and not through collisional ionization. Measurements are reviewed which indicate that PAES can be used to eliminate the secondary electron background by using very low (
