NanoWorld Pointprobe® EFM probes are designed for electrostatic force microscopy. The force constant and the special coating of the EFM type are optimised for this type of application. This type of probe yields a very high force sensitivity, while simultaneously enabling tapping™ and lift mode operation.
All SPM and AFM probes of the Pointprobe® 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. The tip is shaped like a polygon based pyramid.This probe was sold by Veeco Instruments Inc. for over 10 years up until April 2007. Bruker Corporation, which acquired Veeco metrology business, is no longer selling the original probe which has always been manufactured by NanoWorld®.
