In lateral force microscopy (LFM), implemented as frequency-modulation atomic force microscopy, the tip oscillates parallel to the surface. Existing amplitude calibration methods are not applicable for mechanically excited LFM sensors at low temperature. Moreover, a slight angular offset of the oscillation direction (tilt) has a significant influence on the acquired data. To determine the amplitude and tilt we make use of the scanning tunneling microscopy (STM) channel and acquire data without and with oscillation of the tip above a local surface feature. We use a full two-dimensional current map of the STM data without oscillation to simulate data for a given amplitude and tilt. Finally, the amplitude and tilt are determined by fitting the simulation output to the data with oscillation.

The cutting and splitting of carbon nanotube bundles were realized with an atomic force microscopy (AFM) in contact mode. The results of manipulating were found depending on the tip–bundle interaction and bundle–substrate interaction. With an optimal force load of AFM tip, the lateral force applied on the nanotube bundle could overcome the adhesive interaction between nanotubes within the bundle, consequently separating individual nanotubes from the bundle. The threshold of the tip force load was found to be ~45 nN in our experiments. This technique provides new possibilities for the controllable manipulation of carbon nanotubes.
