Knowledge Pack: Thin Film Characterization with AFM

Webinar: Highest Resolution Characterization of Thin Films and Coatings; Topography & Physical Properties

^{RESOURCE TYPE: Video (part of our Thin Films & Coatings Symposium; full on-demand symposium access with knowledge pack)
LENGTH: ~30 minutes}

^DESCRIPTION:
Bruker experts explain how atomic force microscopy (AFM) enables nanoscale characterization of thin films and coatings by directly probing surface structure and local properties. Thin film challenges such as resolving nanoscale heterogeneity, interfaces, and ultra-thin layers are used to frame the need for AFM, and its high spatial resolution, direct measurement approach, and ability to correlate structure with multiple physical properties are presented as key advantages.

Presenters also highlight how these capabilities apply across a range of thin film systems — including polymer layers, semiconductor structures, and 2D materials — showing how AFM reveals structure-property relationships that govern performance.
