Devices in nano-electronics frequently consist of complex two- or three-dimensional structures with complex chemistries. A detailed characterisation thus requires not only a thorough structural characterisation, but also a highly resolved characteris

We have investigated ligand-stabilized Au55 clusters by means of scanning tunneling microscopy (STM) at room temperature on highly oriented pyrolytic graphite (HOPG) and other substrates. Single clusters or groups of several clusters were transferred

Metal nanoparticles (gold, silver, copper) that are embedded in an insulating organic host material exhibit optical plasma resonance absorption in the visible and near-infrared region. The spectral position, the half width and the intensity of the pl

An enhancement of the photovoltaic conversion efficiency of an organic solar cell by incorporation of small metal clusters has been reported recently [1]. The enhancement is explained in terms of resonant light absorption in the metal cluster which i

We set up a simple model for the optical properties of carbon particles in which the particles are considered to be a mixture of two materials-a graphitic and an amorphous material. Several models for the geometrical arrangement of these materials ar

The optical extinction rate of the particle embedded in an absorbing host is defined as a rate of local energy losses caused by the particle (absorption in the particle volume and scattering by the particle-matrix interface) referenced to the matrix

We describe an experimental method to measure the cluster deformation of metal clusters deposited on a substrate. It is based upon the sensitivity of the cluster plasmon resonance on the geometric shape of the clusters; it uses optical spectroscopy w

We report about the observation of intrinsic optical bistability of nanometer‐size spherical CdS particles coated with silver. The particles were chemically prepared as isolated CdS clusters in aqueous suspensions and coated with silver by chemical

Formation of particle aggregates of arbitrary size and shape by lumping of small particles yields extinction and scattering of light that differ from those of isolated particles.
