applications in various fields of nanoscience and nanotechnology.
Keywords: atomic force microscopy; harmonic imaging; materialdiscrimination; mixture ratio; nanocomposites; Introduction
Because of its extreme importance and widespread applications, nanocomposites have received more and more attention [1
, the better the materialdiscrimination. The corresponding contrast values are 0.9, 3.4, 9.8, 11.5, 10.2, 6.5 and 5.5. It is obvious that the harmonic image has the largest contrast and amplitude difference at the set-point of approximately 0.25.
To interpret and ascertain the experimental dependence
almost no sensitivity to material differences.
Materialdiscrimination and mixture ratio estimation
After systematic investigations on the influencing factors, we turn to the application of harmonic imaging in materialdiscrimination and mixture ratio estimation of nanocomposite components. The samples

In this work, we wish to examine the choice of specific higher order eigenmodes for bimodal operation in order to understand if they provide any practical advantages in terms of materialdiscrimination and identification.
