  2. 1. Development of New Experimental Facilities at the Lund Nuclear Microprobe Laboratory

    Author : Asad Shariff; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; low energy tailing; sub-micron beam; PRAM; grid shadow; Kärnfysik; Nuclear physics; GUPIX; Ion Beam Analysis; PIXE; Fysicumarkivet A:2004:Shariff;

    Abstract : Ion beam analysis techniques are now well established as research tools for a broad range of multidisciplinary scientific fields. The ability to focus an ion beam down to micrometer size has expanded and strengthened the capability of IBA techniques to a higher level. READ MORE

  4. 2. Sub-micron Structures in Laser Ablated YBa2Cu3O7-x Thin Films

    Author : Peter Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis treats the epitaxial growth of high-Tc superconductors and other perovskite oxides as well as the patterning of these into sub-micron structures for superconducting electronic devices. A computer controlled laser ablation system, based on a KrF excimer laser (248 nm) to induce ablation, was developed to allow complex thin film growth processes. READ MORE
