Problem solving in the nanometer Range

The surface or exactly the topmost atomic layer is deciding on the surface chemical behavior of a material which controls effects like adhesion, wetting, bioreactions, catalysis etc. An inappropriate chemical situation at a surface can have a crucial influence on desired application or the lifetime of a work piece. As a Service to industrial customers we offer surface related problem solving.

Typical Problems which are related to surfaces are:

  • Adhesion problems
  • Coating delamination
  • Coating delamination
  • Inadequate wetting  (in soldering processes)
  • Degenerating optical coatings in architectural glass
  • Contaminations (in micro fabrication)
  • Contaminations in the nanometer range on electrical contacts
  • Grain boundary embattlement in metals and ceramics
  • Surface activation of polymers
  • Contaminations and quality control of implant surfaces

Surface Analysis will mainly be performed using XPS, AES or any other adequate analytical technique, depending on the problem to solve.
