Conductive Diamond Probes
The contact resonance technology was first developed by the Yamanaka and Arnold groups in the 1990s. The principle is that the AFM cantilever will resonate when it comes into contact with the sample. The cantilever and sample contact can be considered as a spring coupled in series to a second spring and damper in parallel. Here, the first spring represents the elastic response of the cantilever, and the second spring and damper represent the viscoelastic response of the sample.
