Mission statement

The imaging scanning force microscopy is used to reveal the morphology of surfaces and of bulk material (after appropriate preparation). Special techniques allow the spatially resolved estimation of structure-property-relationships.

What we do...

The group offers the characterization of morphology as a service for all scientific departments of the institute. Besides topography it is possible to measure mechanical properties, like Young’s modulus, adhesion, and energy dissipation, as well as electric properties, like conductivity, charge distribution, and surface potential, in high lateral resolution simultaneously and quantitatively. Measurements can be performed at ambient conditions as well as in liquids or in varied humidity. Also, investigations in a temperature range of -35°C to 250°C are possible.

Our core competences are...

Spatially resolved measurements of

  • mechanical parameters  (Young’s modulus, adhesion, energy dissipation),
  • distribution of electric charges or magnetic domains, surface potential, electric conductivity,
  • melting and solidification behavior

The measurements can be done in air, liquids, or gaseous environment, and also with varying humidity by the following methods:

  • contact mode (CM)
  • tapping mode (TM) with phase imaging
  • peak force tapping (PFT) with quantitative nanomechanical analysis (QNM)
  • magnetic force microscopy (MFM)
  • electrostatic force microscopy (EFM)
  • surface potential microscopy (SPoM)
  • torsional resonance mode (TR)
  • tunneling AFM (TUNA)
  • conduct AFM (CAFM)

Collaborations

  • various topics and materials (PB 1, PB 2 and PB 3)
  • MLU Halle-Wittenberg
