NANOSENSORS™ CDT-NCHR AFM probes are designed for non-contact mode or tapping mode AFM (also known as: attractive or dynamic mode). This sensor type combines high operation stability with outstanding sensitivity and fast scanning ability. For applications that require a wear resistant and an electrically conductive AFM 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 AFM tip radius of curvature is between 100 and 200 nm. Nanoroughness in the 10 nm regime improves the resolution on flat surfaces.
