Figure 3.

Plane-view bright-field image (a), dark-field image (b), and the corresponding electron diffraction pattern (c) from sample S-15 min. Rings from Si (substrate) and PtSi structures are revealed in the diffraction pattern. The spherical nanoparticles on the surface (images (a) and (b)) are relatively small and well separated between them.
