Activities

The Laboratory for Surface Analysis is focused on the research and characterisation of solid surfaces, grain and phase boundaries, microstructure analysis, studies of physical and chemical phenomena on the free surfaces of metallic and inorganic materials (adsorption, segregation, oxidation, corrosion, wear, recrystallization, catalysis, thin- and ultra-thin-film analysis) with Auger electron spectroscopy (FE-AES), scanning Auger electron microscopy (SAM), X-ray photoelectron spectroscopy (XPS) and reflection electron-energy-loss spectroscopy (REELS). The laboratory can also perform studies of material structure at the atomic level with transmission electron microscopy (TEM).

  • High-Resolution Auger-Electron Spectroscopy (HRAES),
  • Scanning Auger-Electron Microscopy (SAM),
  • Scanning Electron Microscopy (SEM),
  • X-ray Photoelectron Spectroscopy (XPS),
  • Reflected-Electron Energy-Loss Spectroscopy (REELS).
  • research, development and optimization of the manufacturing of soft magnetic materials and electrical steel sheets,
  • characterization of submicron carbide precipitates in steels and iron based alloys,
  • investigation of the surfaces of metals covered by metallic or non-metallic films by means of "in-situ" analysis and measurements in ultra high vacuum at temperatures of up to 1000 °C,
  • research into the interactions of the gas phase and the solid surface of materials,
  • characterization of thin and ultra-thin films,
  • characterization of surfaces after tribological testing,
  • magnetic measurement of soft-magnetic materials.
