How to use on Bruker® AFM systems

NanoWorld Pointprobe® EFM AFM probes are designed for electrostatic force microscopy. The force constant and the special coating of the EFM type are optimised for this type of application. This type of AFM probe yields a very high force sensitivity, while simultaneously enabling tapping^™ and lift mode operation.

All SPM and AFM probes of the Pointprobe® series are made from monolithic silicon which is highly doped to dissipate static charge. They are chemically inert and offer a high mechanical Q-factor for high sensitivity. The AFM tip is shaped like a polygon based pyramid.

Additionally, this AFM tip offers an excellent tip radius of curvature.

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

PtIr5 Coating

The PtIr5 coating consists of a 23 nm thick platinum iridium5 layer deposited on both sides of the AFM cantilever. The tip side coating enhances the conductivity of the AFM tip and allows electrical contacts. The detector side coating enhances the reflectance of the laser beam by a factor of 2 and prevents light from interfering within the AFM cantilever.

The coating process is optimized for stress compensation and wear resistance. Wear at the AFM tip can occur if operating in contact-, friction- or force modulation mode. As the coating is almost stress-free the bending of the AFM cantilever due to stress is less than 2 degrees.
