Lmm aes spectra
Auger electron spectroscopy is a common analytical technique used specifically in the study of surfaces and, more generally, in the area of materials science. It is a form of electron spectroscopy that relies on the Auger effect, based on the analysis of energetic electrons emitted from an excited atom after a series of internal relaxation events. The Auger effect was discovered independently by … Witrynafore AES to exclude any e ects of the primary electron beam. AES spectra were recorded as rst derivatives and intensities of the lines were taken as the peak-to-peak heights (PPH) of the Auger signals. The GaNf0001gsur-faces were considered to be stoichiometric when the ratio of the N(KVV)andGa(LMM) intensities amounted to 0.79 …
