Abstract:

The surface structure of Cu, Al and γ Al2O3 have been investigated by SEELFS and obtained nearest neighbor distances of the central atoms. The value s compared with those calculated according to theories shows that the errors wer e about 0.01-0.03nm before correcting the phase shifts. These results show the possibility of performing SEELFS technique by Auger electron spectrometer.

Key words: SEELFS(EELPS), Surface analysis, Nearest-neighbor atomic distances, Copper, Aluminum, γ-Alumina
