Image of FIG. 1.
FIG. 1.

(Color online) Representative SEM images of samples processed at 1100 °C‐60 min annealed using the slow heating and cooling stages: (a) sample A1 (Au 5 nm on Si), (b) sample C1 (Au 20 nm on Si), and (c) sample A2 (Au 5 nm on Si) processed at 1100 °C‐60 min annealed using the fast heating and cooling stages.

Image of FIG. 2.
FIG. 2.

(Color online) Representative SEM images of agglomerates of nanodendritic structures in samples annealed using the fast heating and cooling stages at 1100 °C‐60 min: (a) sample A2 (Au 5 nm/Si), (b) sample B2 (Au 15 nm/Si), and (c) sample C2 (Au 20 nm/Si). (d) SEM images of single nanodendritic structures and reconstructions of their contours (to evidence its “tree‐like‐branched” morphology).

Image of FIG. 3.
FIG. 3.

(Color online) Representative AFM images of agglomerates of nanodendritic structures: (a), (b), (c) 3D, 2D images, and line section profile for an agglomerate of the A2 sample. (d), (e), (f) 3D, 2D images, and line section profile for an agglomerate of the B2 sample. (g), (h), (i) 3D, 2D images, and line section profile for an agglomerate of the C2 sample.

Image of FIG. 4.
FIG. 4.

(Color online) (a) SEM image of two agglomerates of nanodendritic structures in the C2 sample. (b) EDX map of the Au, Si, and N relative to the SEM image shown in (a). (c) Schematic picture of composition of the agglomerates.

Image of FIG. 5.
FIG. 5.

(Color online) (a)‐(b) Schematic stages in the formation of the SiO2 NWs (representation of the corresponding changes on the Au‐coated Si wafer where nanowire growth occurs). (c)‐(e) Schematic stages in the formation of the Au NDs (representation of the corresponding changes on the Au‐coated Si wafer where NDs growth occur).
