Thin layers in actinide research
Surfacr science research at the Institute for Transuranium Elements, Karlsruhe is focused on the synthesis and surface spectroscopy studies of thin films of actinides and actinide compounds. The surface spectroscopies used are X-ray photoelectron spectroscopy (XPS) and ultra violet photoelectron spectroscopy (UPS) and Auger electron spectroscopy (AES). Thin films of actinide elements and compounds are prepared by sputter deposition from elemental targets. Alloy films are deposited from corresponding alloy targets and could be used, in principle, as replicates of these targets. However there are deviations between alloy film and target composition, which depend on the deposition conditions such as pressure and target voltage. Mastering of these effects may allow us to study stoichiometric films replicates instead of thick bulk compounds. As an example the composition of U-Ni films prepared from a UNi(5) target is discussed.
