Liquid Contact Resonance Atomic Force Microscopy Via Experimental Reconstruction of the Hydrodynamic Function
Ryan C. Tung, Jason P. Killgore, Donna C. Hurley
We present an experimental method, based on analytical hydrodynamic theory, to accurately predict the inertial and viscous fluid loading forces at arbitrary frequencies in a contact resonance atomic force microscope system. Knowledge of the fluid loading forces present in an AFM system will allow current metrology techniques, formulated for use in air and vacuum environments, to be used in liquid environments. Validation is provided through carefully conducted experiments. The experimental results show that the presented method accurately predicts the hydrodynamic forces present in a surface-coupled atomic force microscope system in both air and liquid.
