Lateral force microscopy on polystyrene-polybutadiene blend
The lateral force imaging mode was used to image local friction differences between the two polymers

This report demonstrates the capability of the FlexAFM in studies of charged solid-liquid interfaces
http://pykmax.com/?p=412 In order to carry out electrochemical(in-situ)AFM experiments, a conductive sample was mounted in an electrochemical liquid cell and connected to a lab-build bipotentiostat. We employed Clavilier-type Au(111) single crystal bead crystal electrodes with facets of micrometer-wide terraces. As examples, we studied the lifting of the Au(111)-(pxV3)reconstruction, surface oxidation as well as the growth and dissolution of copper clusters in sulfuric acid solution.

KPFM using the Nanosurf FlexAFM
Kelvin probe force microscopy imaging
Kelvin Probe Force Microscopy (KPFM) is an extension of AFM. The technique was first published in 1991 by Nonnenmacher and coworkers. Using KPFM, images can be recorded that contain information on the local work function or local contact potential difference between tip and sample.
Although all Nanite systems with an SPM S200 controller and all current Easyscan 2 AFM systems are in principle capable of performing KPFM, the FlexAFM has demonstrated best KPFM performance and is therefore the instrument of choice for this type of measurement.
