Comparative study of solid phase epitaxy (SPE) of iron suicides on Si(001)2×l and boron modified Si(001)4×4-B was conducted for iron coverage, which was varied from 0.6 to 11.3 monolayers (MLs). It was found that annealing of Fe film at 800°C leads to formation of islands of iron suicide, whose type depends on the Fe film thickness. Using reflectio...

Figure 6(a) shows RHEED pattern taken at a small glancing angle of electrons from surface obtained after an- nealing at 800 • C . Two groups of transmission spots were found in the RHEED diffraction pattern that marked by upward and downward arrows. ...

Nodes of network drawn with solid lines in The maximum difference between positions of network nodes (experimental spots) and solid circles (theoretical spots of γ-FeSi 2 ) is observed in [001] γ direction (Fig. 6(b)) that evidences about lattice tension of 3D γ-FeSi 2 islands along this direction. So, found difference between exper- imental (2.79Å79Å) and theoretical (2.70Å70Å) values of inter- layer distance d 001 for γ-FeSi 2 lattice is ∼3.3%. This ten- sion may be connected with γ-FeSi 2 lattice rotation, as said above, at which [001] Si and ...

Some islands (type A) are 3D ones with height of more than 3.5 nm while another islands (type B) are 2D ones with height of ∼1 nm as one can see from the height profile in Fig. 7(b). High islands are connected with γ-phase the presence of which is corroborated by transmission spots in RHEED pattern (Fig. 6(a)). On the other hand, it was found the RHEED pattern in [100] direction (inset of Fig. 7(a)) shows additional (1/2,1/2) streaks with weak intensity, which are connected with type B islands having 2D structure with (2×2) or c(2×2) symmetry. The por- tion of high islands is ∼25%. It is worth to note that after annealing of 1.7 ML of Fe ...
