Diamond AFM Probes
Diamond AFM Probes
Diamond coated AFM tip close-up
Typical radius of uncoated AFM tip
8nm
Resulting AFM tip radius with the coating
<250nm
Full AFM tip cone angle
40°
Total AFM tip height
12-18µm
AFM probe material

AFM tip coating
Conductive diamond
Detector coating
Aluminum
DMD AFM probes feature a thick doped diamond coating. The AFM tip shape is trihedral. The polycrystalline diamond structure ensures extreme durability at the expense of reduced resolution. The coating is also electrically conductive, allowing electrical measurements in contact mode such as Conductive AFM, Tunnelling Current AFM and Scanning Spreading Resistance Microscopy.

HQ:DMD-XSC11
AFM Probe with 4 Different Long Scanning, Conductive Diamond Coated AFM Cantilevers
AFM probes of the HQ:XSC11 series have four different AFM cantilevers, two on each side of the holder chip. They can be used in various applications.
The HQ AFM probes offer high consistency of the AFM tip radius, the AFM cantilever reflectivity and the quality factor.
A wear resistant and electrically conductive doped diamond coating with thickness around 100 nm is applied on the tip side of the AFM cantilevers. The aluminum reflective coating enhances the laser reflectivity of the AFM cantilevers by approximately 2.5 times.
