Improving the accuracy of nanomechanical measurements with force-curve-based AFM techniques

22 Jun 2023

The structure and mechanical properties of sub-micron features in materials are of particular interest due to their influence on macroscopic material performance and function. Atomic force microscopy has the high resolution and force control to directly probe the mechanical properties of a wide range of these materials. In this application note from Bruker, consider the development and implementation of several new features that improve the flexibility, accuracy, and productivity of atomic force microscopes in measuring such important material properties as modulus and adhesion.

Atomic Force Microscopy / Scanning Tunneling MicroscopyAtomic force microscopes (AFM) and scanning tunneling microscopes (STM) are high-resolution forms of scanning probe microscope (SPM) used to generate topological information of a sample down to the atomic scale. Instruments can generate an image of the surface topology, manipulate objects and reveal information on localized properties such as Young’s modulus, conductivity, and magnetism. High-quality STM and AFM probes optimized for your application are available, as well as other SPM-based instruments such as scanning ion conductance microscopes (SICM) & near-field scanning optical microscopes (NSOM).
