Summary form only given. In recent years, nanoparticles of metals, such as gold, silver, and copper, have attracted much attention because they have electrical and optical properties that are different from those of bulk metals. Electron dynamics and optical nonlinear response of metallic nanoparticles have been studied extensively and suggested that metallic nanoparticles are promising candidates...
Summary form only given. Reduction of the size of a material to a nanometric scale leads to drastic modifications of its properties. In metallic systems, they are largely conditioned by the alteration of the conduction electron scattering processes whose study is thus of both technological and fundamental interests. Time-resolved femtosecond techniques have been shown to be powerful tools for their...
