How to optimize AFM scan parameters gear icon

The Point Probe® Plus (PPP) combines the well-known features of the proven PointProbe® series such as high application versatility and compatibility with most commercial SPMs with a more reproducible AFM tip radius as well as a more defined AFM tip shape. The minimized variation in AFM tip shape provides more reproducible images.

NANOSENSORS PPP-CONTAu AFM probes are designed for contact mode (repulsive mode) AFM imaging. This sensor can also be used for force-distance spectroscopy mode or pulsed force mode (PFM). The CONT type is optimized for high sensitivity due to a low force constant. 

The AFM probe offers unique features:

  • metallic conductivity of the AFM tip
  • Au coating on both sides of the AFM cantilever
  • chemically inert

Please note: Wear at the AFM tip can occur if operating in contact-, friction- or force modulation mode.

This product features alignment grooves on the back side of the holder chip.

A metallic layer (Au) is coated on both sides of the AFM cantilever. The AFM tip side coating enhances the conductivity of the AFM tip and allows electrical contacts - the typical AFM tip radius of curvature is less than 50nm. The detector side coating enhances the reflectivity of the laser beam by a factor of 2.5 and prevents light from interfering within the AFM cantilever. The coating process is optimized for stress compensation. The bending of the AFM cantilever due to stress is less than 3.5% of the AFM cantilever length.
