AFM techniques can be broken down into the following general categories: contact, single frequency tapping, multifrequency and 2-pass modes. We will spend 3 afternoons illustrating each case. Piezo force microscopy (PFM) as an example of contact mode, high lateral resolution via higher eigenmodes as an example of single frequency tapping mode, amplitude-modulated, frequency-modulated (AMFM) as an example of a multifrequency technique, and magnetic force microscopy (MFM) and Kelvin probe force microscopy (KPFM) as 2 examples of the 2-pass approach.
