Abstract

We present a microfabricated atomic force microscope (AFM) cantilever that is used to calibrate AFM friction data. The T-shaped lateral force cantilever is equipped with lever-arms that facilitate the application of normal and lateral forces, allowing a calibration to be carried out in situ along with friction measurements. In this work, the torsional spring constant of a T-shaped cantilever has been measured using output data from two different AFM instrument platforms. Torsional spring constant values were found to be within 5% from one instrument to the other, demonstrating the robustness of the lateral force lever technique currently in development.
