Bottom Line: We report on the fabrication and morphology/structural characterization of a porous anodic alumina (PAA)/PtSi nano-template for use as matrix in template-assisted Si nanowire growth on a Si substrate.The PtSi layer was formed by electroless deposition from an aqueous solution containing the metal salt and HF, while the PAA membrane by anodizing an Al film deposited on the PtSi layer.The morphology and structure of the PtSi layer and of the alumina membrane on top were studied by Scanning and High Resolution Transmission Electron Microscopies (SEM, HRTEM).

ABSTRACT
We report on the fabrication and morphology/structural characterization of a porous anodic alumina (PAA)/PtSi nano-template for use as matrix in template-assisted Si nanowire growth on a Si substrate. The PtSi layer was formed by electroless deposition from an aqueous solution containing the metal salt and HF, while the PAA membrane by anodizing an Al film deposited on the PtSi layer. The morphology and structure of the PtSi layer and of the alumina membrane on top were studied by Scanning and High Resolution Transmission Electron Microscopies (SEM, HRTEM). Cross sectional HRTEM images combined with electron diffraction (ED) were used to characterize the different interfaces between Si, PtSi and porous anodic alumina.

Figure 2: Plane-view bright-field image (a) and the corresponding electron diffraction pattern (b) from sample S-5 min. The rings in the diffraction pattern correspond to Si and PtSi structures. No Pt nanocrystals were detected.

Mentions: a) The S-5 min film was amorphous and homogeneous in morphology with a limited surface roughness. The corresponding diffraction pattern showed diffuse rings corresponding to PtSi. These results are illustrated in Figure 2(a, b). In (a) a bright field image is shown, while in (b) the corresponding electron diffraction pattern is depicted. The rings in the diffraction pattern correspond to Si and PtSi, while no Pt nanocrystals were detected.
