Nanostructure of ion-beam irradiated transition layers
|
Fig. 2 shows the cross sectional TEM view of a Fe/Al multilayer. The deposited amounts of Fe and Al were sufficient for single layer thicknesses of dFe= 21 nm and dAl= 11 nm, if no intermixing would occur. The high kinetic energies of the particles (~100 eV) lead to the formation of a bcc solid solution of Al in Fe (not visible here, because it has the same structure than the pure Fe) and an amorphous layer with an average composition of Fe20Al80 between the pure elements during deposition. |
Fig. 3 shows the respective Moessbauerspectrum. Beside the alpha-Fe (cyan), one sees the signals of the bcc solid solution of Al in Fe (green) and the amorphous phase (orange). This little example shows that only a combination of different methods provide the full insight into the structure of the multilayer. For furhter results please see - Highlight- |
