f = 105 kHz | k = 6.2 N/m | tip coating: conductive diamond
Conductive Diamond Coated Tip - Force Modulation Mode - Reflex Coating
NanoWorld Pointprobe® CDT-FMR probes are designed for force modulation microscopy. The force constant of this probe type spans the gap between contact and non-contact mode and is specially tailored for the force modulation mode. The FM sensor serves also as a basis for magnetic coatings.
Furthermore non-contact or tapping mode operation is possible with the FM probe but with reduced operation stability. For applications that require a wear resistant and an electrically conductive tip we recommend this type. Some applications are Tunneling AFM and Scanning Capacitance Microscopy (SCM).
The CDT Diamond Coating is highly doped and the total resistance measured in contact to a platinium surface is 10 kOhm. The typical macroscopic tip radius of curvature is between 100 and 200 nm. Nanoroughness in the 10 nm regime improves the resolution on flat surfaces.
