2. 1. MAX phase thin films : unique multifunctional ceramics with the elements Ti, Si, Ge, Sn, and C

   Author : Jens Emmerlich; Wolfhard Möller; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thin solid films; Single-crystal; Physics; Fysik;

   Abstract : Mn+1AXn phases are ternary carbides or nitrides (X) consisting of an early transition metal (M), and (A)- group element (group III-V). They combine ceramic and metallic properties with high oxidation and thermal shock resistance as well as low resistivity. READ MORE

   Abstract : The objective of this study is to make use of transition metal silicides in a novel way as protective thin films on engineering metals. It can then be possible to take advantage of the potentially good corrosion resistance of metal silicides while compensating for their brittle nature by the ductile bulk material. READ MORE

6. 4. Very thin magnets : X-rays, lasers and spectroscopy

   Author : Jonathan Hunter Dunn; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

   Abstract : The magnetic properties of transition metal films are investigated using synchrotron based x-ray absorption and x-ray photoelectron spectroscopy. These techniques are elementally selective and may therefore be used, either to probe a specific element in a multicomponent system or, as very sensitive magnetometers. READ MORE

7. 5. Fabrication and Corrosion Properties of Nickel Silicides Thin Films

   Author : Eric Tam; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nickel silicides; ion-beam sputter deposition; potentiodynamic polarisation measurements; X-ray photoelectron spectroscopy; corrosion.; thin films;

   Abstract : Surface engineering is a vital issue in engineering materials design. The enhancement of surface properties extends the materials lifetime and improves the materials performance without changing the bulk properties. Thin film deposition is one of the most commonly applied techniques in this field. READ MORE
