Title: Quantitative comparison of two independent lateral force calibration techniques for the atomic force microscope
Published: February 15, 2012
Abstract: Two independent lateral force calibration methods for the atomic force microscope, the Hammerhead (HH) technique and the diamagnetic lateral force calibrator (D-LFC), are systematically compared and found to agree to within 14 % overall uncertainty, using four different T-shaped HH reference probes. The limitations of each method are discussed and investigated. We find that stiff cantilevers may produce inaccurate D-LFC values through the application of excessively high normal loads. In addition, D-LFC results differ when comparing different modes of AFM feedback control, constant height and constant force modes, where the latter is more consistent with the HH method and closer to typical experimental conditions.
