SuperSharpSilicon™ Tip (SSS)
NanoWorld® Pointprobe® NCH probes are designed for non-contact or tapping mode imaging. This probe type combines high operation stability with outstanding sensitivity and fast scanning ability.
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 with a typical height of 10 - 15 µm.
For enhanced resolution of nanostructures and microroughness we have developed an advanced tip manufacturing process leading to unrivalled sharpness of the SuperSharpSilicon™ tip.
This probe offers unique features:
- Typical tip radius of curvature of 2 nm
- Guaranteed tip radius of curvature 5 nm (yield >80%)
- Half cone angle < 10° at the last 200 nm of the tip
For applications requiring lower resonance frequencies or a cantilever length exceeding 125 µm we recommend our Pointprobe® type SSS-NCL.
A trapezoidal cross section of the cantilever and therefore 30% wider (e.g. NCH) cantilever detector side result in easier and faster laser adjustment. Additionally, because there is simply more space to place and reflect the laser beam, a higher SUM signal is reached.
