For the daily use of AFM, the imaging in dynamic mode is more common
the contact mode, because tip and sample are spared.The
students learn the relation between force constant and resonance
frequency, repeat some knowledge about harmonic oscillating systems,
resonances and Q-factors and get introduced to the basics of lockin
amplification technique, which is used to evaluate the amplitudes and
the acquired images, material contrast can be obtained in the phase
image in addition to the topography.
