Elastische Elektronenstreuung im Energiebereich 100–150 keV

The angular dependence of elastic scattering of 100 to 150 keV electrons has been measured for scattering angles of 5 ° to 165 °. The atomic numbers of the scattering atoms were 6 and 79. Within the experimental errors (few per cent) we found agreement with the results of the calculations of Lin.

Nuclear probes in the materials science of solar cells

We present background material about solar cells and the copper-indium-sulphur system and then discuss three important processes for the production of CuInS₂ solar-cell material. These include: sulphurization of metallic copper-indium precursors, physical vapour deposition of the elements, and three-source molecular beam deposition. Using perturbed angular correlations with the¹¹¹In-¹¹¹Cd probe, we are able to identify the indium-containing phases of the system and thus to characterize the cited production processes. The prospects of nuclear probe methods in the development of solar-cell materials are discussed.
