Abstract
The technique of impact collision ion scattering spectrometry (ICISS) was used to study the composition and structure of the NiSi2(111) type B surface. Comparison of experimental data with computer simulation indicates that the surface consists of a Si bulk termination of the fluorite structure with an additional Si bilayer on top. These results are consistent with an additional Si bilayer model proposed from photoemission and scanning tunneling microscopy studies.Keywords
