原始语种摘要: Abstract(#br)The iron silicide has various interesting phases both fundamentally and technologically, which have acquired much attention to date. Iron silicides are often fabricated on a Si substrate by a solid phase epitaxy method, and the initial stage of intermixing of iron atoms with substrate Si is of crucial importance for silicide fabrication, which remains to be clarified. Here, we have investigated the initial stage of the iron-silicide formation before crystallization with Mössbauer spectroscopy suited to characterization of magnetic and chemical properties of 57 Fe atoms in materials. The sample was prepared by deposition of 57 Fe of 1nm on a Si(111) surface at 450K. Conventional Mössbauer spectroscopy in the energy domain revealed presence...
