There are several advantages to using multi frequency AFM over traditional single-frequency AFM:
Enhanced Sensitivity: By operating at multiple frequencies, it is possible to detect finer details and subtle variations in the sample's properties. Multimodal Data: Simultaneous acquisition of different types of data (e.g., topography, mechanical properties) enables a more comprehensive understanding of the sample. Better Resolution: Higher harmonic frequencies can provide better spatial resolution, allowing for the observation of nanoscale features. Quantitative Analysis: The technique allows for the quantitative measurement of mechanical properties such as stiffness and adhesion.
