Graphical Abstract
  • real periodic surface structure differently for a different scan direction (see Figure 2a,d). As we know that the real surface structure is, indeed, independent of the scan direction, we can use the difference between distortions to calculate the drift velocity (and the real surface structure) as
  • of features or corresponding lattice points. With unDrift, however, the images in Figure 4a,b can be drift-corrected easily, as algorithm I works reliably even for very high drift velocities. We present the drift-corrected images corresponding to the images in Figure 4a,b in Figure 4c,d, respectively
  • . Note that we cut the drift-corrected images to fit the form factor of this figure, while still being able to see the atomic structure. Figure 4c,d shows that the unit cell dimensions in both up and down image are now almost identical, and the surface now appears to be hexagonal. We find lattice
