    • note
    • Here, the surface morphology refers to the size, shape, and spatial distribution of metal particles that are either supported on a substrate, such as Ag islands on a glass slide, or merged with a substrate, such as protrusions on an electrochemically roughened electrode surface. A related term, namely, "surface roughness", has a more narrow meaning: it only defines an average particle size and does not necessarily include a connotation of spatial distribution.

    • SERS from colloidal Ag particles has been observed under a spectroscopic microscope. However, the detected signal might result from a cluster of particles since higher resolution images of the observed spots were not reported. See, for example, (a) Emory, S.

    • note
    • The Ag particles shown in Figures 4 and 5 were deposited at 500 and 470 mV, respectively. These values are higher than the theoretical threshold of 425 mV. We think that the difference is caused by liquid junction potential and other factors associated with a non-ideal reference electrode.

    • We obtained this value by ignoring the local surface roughness and assuming a closely-packed SAM of (√3 × √3)R30 lattice on an Ag(111) surface. The (√3 × √3)R30 lattice distance can be calculated from the nearest neighbor distance of an Ag fee crystal (2.89 Å).

    • The laser spot size was measured following the method in ref 32. The measurement uncertainty is primarily determined by the resolution of the one-dimensional micrometer (0.1 μm) used in the measuring apparatus.
