FIG. 1.

(a) STM image (50 × 50 nm2) of the Mn nanoclusters formed on Si(110) by deposition of 1 ML Mn at RT. (b) STM image (900 × 900 nm2) of the MnSi∼1.7 NWs formed on Si(110) by deposition of 2 ML Mn at 550 °C.

Image of FIG. 2.
FIG. 2.

XPS survey spectra for (a) the Mn nanoclusters and (b) the MnSi∼1.7 NWs formed on the Si(110) surfaces.

Image of FIG. 3.
FIG. 3.

Mn 2p region of the XPS spectra for the Mn clusters and the MnSi∼1.7 NWs formed on the Si(110) surfaces. The Mn 2p spectra of pure Mn and MnO taken from Refs. 17 and 18 , respectively, are also shown as a comparison.

Image of FIG. 4.
FIG. 4.

The best fit spectra for the Mn 2p core levels taken on (a) the Mn clusters/Si(110) and (b) the MnSi∼1.7 NWs/Si(110) samples. The open circles are the experimental data and the thick solid curves (red) overlapping them are the results of the fits. The component peaks are displayed underneath each spectrum. The residuals of the fits are shown by the lowermost solid lines (black) in (a) and (b).

Image of FIG. 5.
FIG. 5.

Si 2p region of the XPS spectra for (a) the bare Si(110), (b) the Mn clusters/Si(110), and (c) the MnSi∼1.7 NWs/Si(110) samples. The open circles represent the experimental data and the thick solid lines (red) overlapping them are the fits to the data. The components to the respective Si 2p core-levels are displayed underneath each spectrum. The blue line (P1) and the magenta line (P2) represent the bulk and surface contributions, respectively, of the Si(110) substrate. The cyan line (P3) represents the contribution from the silicide phase. The residuals of the fits are shown by the lowermost solid line (black) in each figure.

Image of FIG. 6.
FIG. 6.

XPS valence-band spectra taken on the bare Si(110), the Mn clusters/Si(110), and the MnSi∼1.7 NWs/Si(110) surfaces.
