SPECS Nanonis Atom Tracking Software Module

The atom tracking module is designed to track topographical features (not only atoms) dynamically and can therefore measure and compensate for thermal drift and sample tilt. A fully automated procedure automatically calculates drift velocity and sample tilt in both X and Y-directions as well as drift in Z-direction and compensates for these. This module is of particular interest when the tip position has to follow a local extremum (e.g. an atom or molecule, maximum or minimum) between point-spectroscopy or when scanning a small scan area where drift is highly noticeable.
