Figure 3From: Porous anodic alumina on galvanically grown PtSi layer for application in template-assisted Si nanowire growth 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.Back to article page
