In an ever-advancing miniaturization of our modern, high-tech world, thin films and multi-layered materials gain increasing attention as they could pave the way to novel applications like ultra-thin ferroelectrics, protective coatings with adjustable friction, or tailored conductive properties [1-3]. In this sense, the thinnest films imaginable are single layers of 2D materials like graphene, hexagonal boron nitride (hBN), or transition metal dichalcogenides (TMDs) like (tungsten disulfide) WS2. However, reliable application of such nanometer-sized structures requires a correlative metrology that resolves such features [4].
Here, atomic force microscopy (AFM) has been established as a most versatile tool for the characterization of structures and interfaces with sub-nanometer resolution. The unique utilization of a nanometric probe in close proximity to the sample allows for a series of advanced characterizations of the material properties beyond crucial topographical information such as step height, roughness, and lattice periodicity. Nanomechanical measurements to map the adhesion, stiffness, or even friction with unparalleled high resolution can be performed. The ability to apply a bias locally permits to correlate these properties with additional features like the work function and conductance. This provides a comprehensive investigation of morphology and defects with a broad spectrum of local information, which helps to optimize the preparation and development of new materials. Lastly, a high degree of automation enables AFM systems to program batch processes for wafer sampling, e.g. to study sample degradation vs. time caused by various factors, including illumination or humidity.
In this talk, we demonstrate the versatility of AFM via a nanoscale characterization and manipulation of switchable ferroelectric domains in hBN/graphene heterostructures. Moreover, we assess the correlation between the presence of defects on graphene coatings and the variation of the local surface potential. Finally, we show how scanning probe electrochemical experiments are able to correlate surface reactivity with the chemical composition and arrangement of multi-layers.

About the European Materials Research Society:
E-MRS now has more than 4,000 members from industry, government, academia and research laboratories, who meet regularly to debate recent technological developments of functional materials. The E-MRS differs from many single-discipline professional societies by encouraging scientists, engineers and research managers to exchange information on an interdisciplinary platform, and by recognizing professional and technical excellence by promoting awards for achievement from student to senior scientist level. As an adhering body of the International Union of Materials Research Societies (IUMRS), the E-MRS enjoys and benefits from very close relationships with other Materials Research organizations elsewhere in Europe and around the world.
