ABSTRACTFe-Silicides were formed by annealing MBE-deposited thin Fe layers with a thickness in the range of 24 Å on (7x7) reconstructed Si(l11) substrates. Samples suitable for depth-selective investigations by CEMS (Conversion Electron Mössbauer Spectrometry) were prepared by using only the 57Fe isotope for a few monolayers of the total Fe film, and depositing these selectively right at the interface or separated from it. During the growth the substrate was held at room temperature. The silicide formation upon annealing to temperatures up to 900°C was monitored in situ with RHEED. From the CEMS studies a drastically different sample composition was inferred as a function of monolayer distance from the interface for the as-deposited samples and for annealing temperatures up to 400°C. Analysis of these spectra indicates the presence of metastable and stable iron silicides.
