ABSTRACT

Ferroelectric materials are widely used in modern electronic devices, from capacitors to data storage, sensors, transducers, and sound emitters.
These materials exhibit a spontaneous and switchable electric polarization that arises from a non-centrosymmetric arrangement of positively and negatively charged atoms within the crystal structure, which leads to a permanent electric dipole. A wide range of different components can be applied, ranging from classic components like metal oxides in a perovskite structure such as barium titanate or lead zirconate titanate to soft polymers like PVDF. In this talk, we provide an overview and introduction to three different modes of piezo force microscopy: off-resonance single-frequency PFM, resonance-enhanced single-frequency PFM, and dual-frequency resonance tracking (DFRT) PFM. We briefly discuss the advantages and disadvantages of these modes and demonstrate how they can be combined with a force-distance-curve-based mode to avoid lateral shear force and enable destruction-free imaging of various material properties such as adhesion and stiffness, as well as piezoelectricity on a local scale. Finally, we provide an outlook on how such investigations can be combined with other modes of the broad family of atomic force microscopy, like Kelvin probe force microscopy, by characterizing and switching ferroelectric domains in hBN/graphene 2D heterostructures. Accordingly, we present the versatility of AFM-based techniques to provide a comprehensive analytical toolbox for a large variety of samples.
