A NOVEL FORCE-SENSING ARRANGEMENT FOR COMBINED SCANNING FORCE SCANNING TUNNELLING MICROSCOPY APPLIED TO BIOLOGICAL OBJECTS

摘要

The force and compliance upon scanning tunnelling microscopy (STM) of macromolecular specimens and the conductivity of the specimens upon scanning force microscopy (SFM) have been studied, using a hybrid scanning force/scanning tunnelling microscope. Unlike conventional force microscopy, the sample lies on top of the force sensor. This gives full freedom in the choice of the shape, size and material of the probing tip. Hence, the set-up is well suited for those combined scanning probe microscopies, where the probe to sample distance must be kept constant while some property of the sample is measured locally in its near field.
