AR5-NCH

High Aspect Ratio (> 5:1) - Non-Contact/Tapping Mode - High Resonance Frequency

NANOSENSORS™ AR5-NCH AFM tips are designed for non-contact mode or tapping mode AFM. This probe type combines high operation stability with outstanding sensitivity and fast scanning ability.
For measurements on samples with sidewall angles approaching 90° NANOSENSORS™ produces specially tailored tips. These tips are FIB (Focused Ion Beam) milled to achieve a high aspect ratio portion better than 5:1 at the end of the common silicon tip. This subtractive method of producing the high aspect ratio needle offers the advantage of high lateral stiffness and rigidity of the tip.

The probe offers unique features:: - length of the high aspect ratio portion of the tip > 2 µm; - typical aspect ratio at 2 µm in the order of 7:1 (when viewed from side as well as along cantilever axis); - (when viewed from side as well as along cantilever axis!); - half cone angle at 2 µm of the high aspect ratio portion typically < 5°; - guaranteed tip radius of curvature < 15 nm; - monolithic tip; - highly doped to dissipate static charge; - high mechanical Q-factor for high sensitivity
