Silicon based beam deflection AFM cantilever for electrostatic force mode. Rectangular AFM cantilever that is shaped like an arrow. PtIr5 coating on both sides. PtIr-coating on both sides. Wide detector side for easy adjustment of the detection system, small width at the AFM tip side reduces damping.

All AFM probes of the Arrow™ 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. These AFM probes feature a rectangular AFM cantilever with a triangular free end and a tetrahedral AFM tip.

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

The unique Arrow™ shape of the cantilever allows easy positioning of the AFM tip on the area of interest.

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.
