Abstract

We consider driven oscillations of the AFM cantilever in computational experiments. Complexity of motion is described by permutation entropy H(3), which we compute for data obtained during scanning. Our aim is to find the optimal values of the scanning velocity, initial position of the tip, and the driving force amplitude and frequency for imaging the nanostructure, in a specific dynamic mode of the AFM operation.
