Our Pillar probes offer an ideal solution to robust imaging of samples with features with aggressive aspect ratios. Each probe consists of a cylindrical shaped pillar tip made of strong and conductive single crystal diamond.
Highly doped with boron with a macroscopic resistivity of 0.003 - 0.005 Ω∙cm
Typical contact resistance of 10 kΩ depending on contact radius (measured on a silver surface)
Gold reflex coating on the detector side of the cantilever to enhance reflectivity
