Image of FIG. 1.
FIG. 1.

Scanning electron microscopy images of samples with a low (a) and a high (b) coverage of gold nanoparticles after immersion into diluted and undiluted colloidal solution, respectively. The size of the images is .

Image of FIG. 2.
FIG. 2.

Relative dc conductivity of silver layers deposited on thick oxide samples with a high gold nanoparticle coverage, obtained by four-point probe measurements. represents the bulk dc conductivity of silver which amounts to . The dashed lines are a guide to the eye.

FIG. 3.

Ellipsometry spectra of silver deposition for 0 s (dotted), 30 s (dashed), 1 min (dash-dotted), 2 min (dash-dot-dotted), and 5 min (solid) on a gold-seeded silicon/silicon oxide sample.

Image of FIG. 4.
FIG. 4.

Pseudodielectric functions after silver deposition for 0 s (dotted), 30 s (dashed), 1 min (dash-dotted), 2 min (dash-dot-dotted), and 5 min (solid), obtained by direct inversion of the spectra in Fig. 3, assuming a two-phase system.

Image of FIG. 5.
FIG. 5.

Effective thickness of the layer as a function of silver deposition time, obtained from the fits. Results for high gold coverage (squares/triangles) and for low gold coverage (circles) are shown.

Image of FIG. 6.
FIG. 6.

Electron density as a function of silver deposition time, for high gold coverage (squares/triangles) and low gold coverage (circles). The dashed line represents the electron density as determined for bulk silver.

Image of FIG. 7.
FIG. 7.

Fit results of the relaxation time for silver deposition on high (squares/triangles) and on low gold coverage samples (circles).

Image of FIG. 8.
FIG. 8.

Fit results for the resonance energy , for silver deposition on samples with high (squares/triangles) and low gold coverage (circles).

Image of FIG. 9.
FIG. 9.

Relative optical conductivity as a function of silver deposition time on samples with high (squares/triangles) and low (circles) gold coverage.

Image of FIG. 10.
FIG. 10.

Comparison of the electron density and resonance energies obtained from fitting our ellipsometry spectra to the Maxwell–Garnett model in Eq. (5) as presented by Yamaguchi (see Ref. 1). The symbols pertain to different series of experiments. The solid line represents the linear relationship (on a log scale) and the dashed lines are a guide to the eye.

Image of FIG. 11.
FIG. 11.

Effective parallel depolarization factors as a function of the silver deposition time, for high (squares/triangles) and low (circles) seed particle density. The values have been calculated from the resonance energies in Fig. 8 using Eq. (8). The dashed lines are a guide to the eye.
