Abstract

 

The NIST ‘Hammerhead’ lateral force cantilever enables precise nanoscale friction measurement capabilities for Atomic Force Microscopy (AFM). The Hammerhead cantilever is equipped with lateral lever arms that facilitate the application of normal and lateral forces, comparable to those acting in a typical AFM friction experiment. The Hammerhead allows both calibration and friction measurements to be carried out in situ and the user to select acceptable measurement precision via a potentially unlimited number of calibration measurements across the full working range of the AFM photodetector. The Hammerhead is compatible with typical commercial AFM instrumentation and allows for common AFM techniques such as topographic imaging and other surface force measurements to be performed.
