Solid nano-scale particles are of high interest because of their unique electrical, optical, catalytic and magnetic properties that implicate numerous innovative technical applications. The highly-specific synthesis of particles with customized composition, size and morphology takes place in flame-, plasma-, and wall-heated reactors. The resulting particles are characterized by spectroscopic methods, as well as by BET and TEM analysis. The underlying kinetics of particle formation as well as the physical characterization and the implementation in electronic systems are investigated within SFB445 and the Center of Nano-Integration Duisburg Essen (CeNIDE).
