Surface Characterisation

In our laboratories, we have a variety of surface analytical techniques at our disposal. The individual techniques are different - but complementary - with respect to the kind of information that is obtained, the requirements for the sample condition, and the demands on the operator's skills. Generally, surface analytical techniques can be grouped as follows:

  • Optical characterisation of surfaces (e.g. light microscopy)
  • Chemical characterisation of the surface or of the surface near bulk regions
  • Characterisation of the surface topography

Inherently, surface analytical techniques can also be applied to nanoanalysis, because the surface takes a more and more important role as structural dimensions grow smaller.
