A new technique for synthesizing Fe nanoparticles based on an electron beam deposition
technique from a Fe2O3 source has been developed. We deposited Fe2O3 films directly
on Si(001) substrates, Al and Cu buffer layer, and observed the formation of Fe nanopar-
ticles at the Si(001) and Al interfaces respectively. The Al at the interface is oxidized
to Al2O3 and Si is oxidized to SiO2. For films deposited on Cu buffer layer, however,
no Fe nanoparticles were formed. We explain our results in terms of the enthalpy of
formation of the oxides. The enthalpy of formation of SiO2 and Al2O3 is much lower
than that of Fe2O3, thus promoting the formation of Fe nanoparticles. The enthalpy of
