Vibrational analysis of the cantilever in non-contact scanning force microscopy
Result description
SFM is based on detection of forces between an observed sample surface and a sharp tip located on the end of cantilever. In non-contact mode the changes of effective resonant fraquency of the cantilever with a distance between the tip and surface is utilised for imaging the nanostructure objects. The forces having decisive influence in the non-contact mode of UHV SFM van der Waals attractive forces between the tip and surface atoms. We simulated resolution limits of the non-contact method based on theseforces - to describe the interaction between the tip and testing surface structures we considered the tip of conical shape terminated by a spherical cap. The surface was modelled by an infinite surface plane bearing atomic scale objects (nanostructures).
