Description

RBS/Channeling, Sputtering/RBS and SIMS analysis have been performed on the MBE-grown Si/GexSi1-x multilayer. The thickness, atomic ratio and crystalline perfectness of the epitaxial layer are determined by 2 MeV 4He+ RBS/Channeling analysis. By sputter etching of the sample with low energy Ar+ ions, the thickness of epitaxial layer is reduced. Then RBS analysis of 2 MeV 4He+ ions on the etched sample yields information about the deeper layers, the interface of the multilayer samples and the concerned phenomena induced by sputter etching. The periodical structure of Si/GexSi1-x multilayer samples is clearly identified by the SIMS analysis before and after sputter etching
