Abstract :
We have established an occurrence of modulated surface structures that are more marked on Ag than Au nanoparticles (NP) respectively deposited on indium tin oxide (ITO) substrates. It has been observed that the period of the structure features strongly depends on the resistivity of the substrate involved. AFM investigations showed that the structure period changes between 1.15 and 3.39 µm and substantially depends on the pulse frequency and the wavelength of the irradiation light. The origin of the phenomenon observed is given in the framework of the photo-thermal effects.
