Rocky Mountain Nanotechnology, LLC, is the only company that manufactures and sells ultra-sharp, solid platinum and platinum-iridium AFM probes, for high resolution electrical measurements. These probes can be used in various modes, including tapping and contact and are ideal for C-AFM, EFM, KPFM PFM, SCM, SMM, SMIM, and SNOM applications. Each probe is imaged by FE-SEM to verify its tip radius. The probes have cantilever frequencies from 4.5kHz up to 100kHz. They also have a long lifetime and high reliability in electrical measurements. There is never an issue with conductivity because the probe tips are purely metallic.
