Title: Friction coefficient mapping of 2D materials via friction-induced topographic artifact in atomic force microscopy
Authors: Thales Fernando Damasceno Fernandes
Bernardo Ruegger Almeida Neves
Abstract: This work explores an atomic force microscopy artifact that yields different topographic data depending on the scanning direction in contact mode. Such artifact is associated with differences in friction coefficients across the sample, which leads to up to 500% difference in topographic data of 2D materials. An analytical theory is used to explain quantitatively this artifact. Nevertheless, on the bright side, such artifact also yields a straightforward methodology, which effectively maps friction coefficients across any 2D material without the need of cantilever spring constant calibration.
