Determination of the morphology of Ag deposits by photoreflectance

Abstract
The optical response of one Ag monolayer deposited on different Si surfaces has been studied by differential reflectance spectroscopy. The observation of the plasma resonance in the Ag deposits and its energy position, or the nonobservation of this plasma resonance, allows a qualitative determination of the morphology of the thin Ag film: either continuous or formed by quasispherical particles or by flattened three-dimensional particles.
