Research Topics

The imaging scanning probe technique is used to reveal the morphology of surfaces and of bulk material (after appropriate preparation). Special techniques allow the 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)

Equipment
