AFM Cantilever Shape
Rectangular (diving board) AFM cantilevers are the most widely used as the approximate values of their spring constants and resonance frequencies can be easily calculated from their dimensions. Generally, any rectangular AFM cantilever can be produced with any required type of the AFM tip with a few exceptions.

Application
The rectangular shape is the best in terms of Q-factor, regularity of the resonance curve, and ease of use. The simplicity of the geometry allows making some approximate calculations of some important parameters of the AFM cantilever like torsional and flexural force constants. These AFM probes are suitable for both contact and oscillatory AFM modes.
