Contact Mode
- Contact Mode measurement on SnO2, 3 x 3 µm2, max. height: 230 nm
Contact Mode is the most straightforward, basic topography imaging mode of the AFM.
In contact mode, the AFM tip has a direct contact with the sample. While the tip is scanned along the surface, the sample topography induces a vertical deflection of the cantilever. This deflection is measured by a fiber- optical interferometer. An active vertical feedback system maintains a preset load force (= static deflection) on the cantilever.
Contact Mode - basis for further SPM techniques
Contact Mode is suitable for materials science, biological applications and basic research. It also serves as a basis for further SPM techniques, which require direct tip-sample contact. Contact Mode imaging is part of the basic configuration of the NANOS and N8 product series.
