Nanomechanical Testing

High-Resolution In-Situ SPM Imaging

Superior nanomechanical testing results

Bruker is the pioneer of in-situ Scanning Probe Microscopy (SPM) imaging, which directly couples nanomechanical and nanotribological characterization with high-resolution SPM imaging. The in-situ SPM technique utilizes the same probe to image the sample surface as is used to conduct the test, allowing images to be quickly gathered on-site without leaving the test location. Bruker’s in-situ SPM imaging inherently increases accuracy, repeatability, and speed of testing since ex-situ imaging methods, such as operating an AFM in parallel, requires additional time in moving the sample to another imaging location and presents significant challenges associated with reliable positioning on the desired testing sites.

Scan size and resolution of vertical and horizontal axes can be changed independently: 30 μm x 30 μm scan size, 256 x 256 resolution (top); and 60 μm x 30 μm scan size, 512 x 256 resolution (bottom).

Nanometer Precision Test Placement Accuracy

Bruker’s in-situ SPM imaging provides an imaging resolution on the same length scale as the testing, enabling truly quantitative and accurate characterization at the nanoscale. Pre-test SPM imaging of the testing site enables direct measurement of surface morphology (e.g. microstructure, topography, roughness) with nanometer resolution and is critical for avoiding surface defects prior to testing. High precision ±10nm test position accuracy streamlines testing of multiphase materials and allows the direct correlation of microstructure (e.g. shape, size, or distribution of domains) to mechanical properties. Additionally, post-test SPM imaging provides quantitative characterization of material deformation behavior (e.g. fracture, pile-up) and verification of the test placement.
