    • Inert cathodes, provided with a catalytically effective thin surface coating, enabling oxygen reduction are suitable for fuel cells. However, in the presence of methanol as a combustible, this coating must exhibit selective properties which cannot be obtained by using semiconductive cluster materials made of transition metal chalkogenides in the form of powder or a fine coating. The inventive inert cathodes possess the desired catalytic and selective properties. Their thin surface coating comprises colloidally dispersed homogenously distributed clusters and its production requires only a minimal amount of material in the nanogram range for a low coverage rate with a highly selective and catalytic degree of action. The coating is obtained by immersion in a colloid containing the cluster mixture and a stabilizer in a solvent.The solvent and stabilizer are removed by temperature treatment after application of the colloid.

    • Silicon-based semiconductor components - solar cells, protodectectors, LEDs - can be made with a porous layer on the adjacent substrate surface. Porous silicon can be produced by the electrochemical surface modification of flat silicon bodies. The physical properties of ultra-thin layers with nanoporous structures and their electrical or optical and opto-electric properties of high quality can be obtained. The production processes are compatible with preparation measures for other purposes. Such porous layers UPSL are ultra-thin - 20 to 100 or 150 nm - with pore diameters of up to 10 nm. Homogeneity is attained in both features. In addition, the type of conductivity and the doping concentration of the substrate material are independent. Said material may, for example, be pure Si, SiC or SiGe; it is single or polycrystalline and p conductive (solar cell, photodetector) or n conductive (LED). Layer thicknesses can be predetermined if a 0.1 to 0.7 molar aqueous electrolyte with a pH of 3.5 +/- 0.5 is used and the maximum anodisation current is kept between 0.3 and 2.1 mA/cm depending on its concentration. The treatment time can be adjusted via a reference value of flowed electric charge per unit area.

    • Semiconductor wafers for the production of electronic components must have a surface as perfect as possible for subsequent processes. For that purpose a flat n-Si body is electrolytically polished in a fluoride-containing electrolyte solution to which is applied an anodic potential while the surface to be treated is irradiated with light whose energy is at least equal to that of the band gap, or a flat p-Si body is similarly treated in a dark environment. At the same time, an electroanalytic monitoring process is carried out to detect the occurrence of a periodic current oscillation. The surface is polished during a few such current oscillations. The treatment comprises in particular the anodic oxidation and electrochemical etching of the surface, if required also an electric polishing process, and allows a high electronic quality characterised by the interface state density to be obtained by immediate hydrogen termination during the transient dark current that sets in.
