| Pulsed Laser Deposition: Possible Problems for the Deposition of Energy Materials |
| Speaker: | Thomas Lippert (PSI Center for Neutron and Muon Sciences, Villigen/Switzerland) |
| Abstract: | Thin film deposition by pulsed laser deposition (PLD) is on the verge or is already an established tool for industry, e.g. for X-ray mirrors and high Tc superconducting tapes, but for a wider application several shortcomings must be overcome. These problems, e.g. differences in composition between targets and thin films, non-homogenous composition of the thin films, and deviation of the film thickness for substrates greater than around 1 cm2, are most likely related to the ablation plume. A detailed study of the ablation plume can therefore help to understand whether and how these problems can be overcome. We apply space-, angle-, and energy-resolved plasma mass spectrometry, space- and angle-resolved ion probe measurements, and spectral- and time-resolved plasma imaging in the same PLD chamber, that is equipped with a special designed substrate system to analyse the thin films composit |
