The attenuation of far-infrared (λ=0.119 mm) surface plasmons has been measured as a function of the thickness of a silicon overlayer on top of silver. Good agreement with theory was obtained indicating that the Drüde model for the dielectric constant of silver is valid out to these wavelengths.

    The wavelength dependent photochemical cross sections for three adsorbates (OCS, NO, SO[sub 2]) on roughened silver have been measured, and contrasted with the behavior on Ag(111). Surface roughness leads to significant enhancements of the photochemical cross sections for all three adsorbates....

    Controlling separately the launching of surface plasmons and their recovery as freely propagating light is essential for the development of surface plasmon photonic circuits. With this target in mind, we have studied in the near-field the launching of surface plasmons in a well-defined direction...

    The interaction of a Cl[sub 2] plasma with a Si(100) surface has been investigated by angle resolved x-ray photoelectron spectroscopy (XPS). It was found that the amount of chlorine incorporated into the near-surface region of Si increases with ion energy, and does not change with long exposure...
