  1. Probes • Probe trade offs • Probe Fabrication • Probe selection • Unknowns about mechanical properties of probes AFM Lab

  2. Elements of a Basic Atomic force Microscope AFM Lab

  3. AFM Resolution AFM Lab

  4. FIGURE 2-37 SiN cantilevers are typically triangular with two arms meeting at an apex. The probe on SiN probes are typically pyramidal and appear hollow at the top. (Top) Si cantilevers are typically rectangular and the probes tend to have a triangular shape to them. Si probes are crystalline and are prone to chipping and breaking if they crash into a surface.
