Tip Specification
AD-2.8-SS Tip Image
Highly conductive Apex Sharp diamond probes, formed by a unique patented process ensure the best possible nanomechanical and electrical performance. These tips are sharper and last longer than any other electrical AFM probe. The conductive diamond coating is highly doped with boron which leads to a macroscopic resistivity of 0.003 - 0.005 Ohm·cm. Contact resistance is typically 10 k? depending on contact radius measured on a silver surface. By using wear-resistant sharp diamond probes the contact size is well characterized and stays constant during mechanical measurements. Quantitative and repeatable measurements for over 24 hours of continuous use have been demonstrated with these probes. A gold reflex coating deposited on the detector side of the cantilever to enhance the reflectance of the laser beam.
