Original Abstract

The presented work describes a finite element method based modeling of a conductive AFM measurement process. The C-AFM is a scanning probe microscopy technique for mapping electrical properties of a sample together with its topography. The contact resistance between the probe and the rough surface is modeled in two steps - first the problem of mechanical deformation is solved and then the electrical field, and current, is found. The geometry of the model comes from a real sample topography measured using AFM. The whole multiphysics 3D simulation is done for each data point, which makes the problem possible to be solved only using a supercomputer with many simplifications and optimizations.
