Abstract

original image

Completely new materials arise when semiconductor nanoparticles are periodically ordered in superlattices. First pioneering preparations of such superlattices were achieved by self-organization of ligand-stabilized CdSe and CdS nanoparticles. The block polymerization to give micelles in the presence of gold salts and their reduction by the electron beam of a transmission electron microscope (TEM) led to ordered gold clusters. The picture on the right shows a TEM image of a material of this type.
