Technical Workshop on Kelvin Probe Force Microscopy

This satellite meeting of the NCAFM 2008 conference in Madrid is focused on Kelvin Probe Force Microscopy (KPFM) and on closely related techniques. It will take place on Monday, September 15th, 2008 from 2PM till 6PM, exactly one day before the beginning of the NCAFM Conference.

We observed an increasing number of contributions in the field of KPFM in the last years. Recently, also high resolution experiments showing molecular and atomic contrast on various substrates. The physics as well as the imaging mechanism behind these measurements are still not well understood. Furthermore, there are still many questions concerning KPFM such as the limits of special and electrical resolution and cross talk between the topographical and electrical signals.

The workshop will provide a platform to discuss these technical and fundamental aspects of this special field of scanning probe microscopy (SPM) in detail. For this purpose, outstanding scientists working in that field will present their work in talks to stimulate and provoke the discussion. The target groups of the workshop are theoreticians and experimentalists working in SPM, nevertheless newcomers and students will have the chance to get a comprehensive overview in the field of KPFM. The main topics discussed will include:



  • physical and technical aspects of AM- and FM-mode KPFM
  • absolute determination of the work function/surface potential
  • towards the understanding the atomic contrast in KPFM
  • connection between topographical and electrical signals
  • new applications and techniques related to KPFM
  • development of adequate theoretical models
  • simulation of KPFM experiments
