Image of FIG. 1.
FIG. 1.

(a) Schematic of a sample structure with a description of fabrication processes. (b) Scanning electron micrograph of pitch HSQ lines on the Au surface.

Image of FIG. 2.
FIG. 2.

Scanning electron micrographs of pitch Au gratings. (a) Large-area view, (b) tip area, (c) tilted view, and (d) zoom-in view at the middle. (e) Another pitch Au gratings obtained in a different experiment by the same fabrication process. The pictures of (d) and (e) were taken at the same magnification.

Image of FIG. 3.
FIG. 3.

Raman spectra of -diethyl--cyanine iodide on the Au gratings, Au film, and oxide surface. The inset briefly illustrates Raman measurements with Au gratings.

Image of FIG. 4.
FIG. 4.

Scanning electron micrographs of pitch Au gratings with various gaps (duty cycles). The scale bars represent all . (a) gaps (50% duty cycle), (b) gaps (70% duty cycle), (c) gaps (85% duty cycle), and (d) nearly no gaps ( duty cycle).

Image of FIG. 5.
FIG. 5.

Raman spectra of -diethyl--cyanine iodide on the Au gratings described in Figs. 4(a)–4(d). For gaps, Raman data with time delay are also shown for comparison.
