Special handling information for NANOSENSORS™

Due to their unique geometry the tips of the are more susceptible to tip damage by electrostatic discharge (ESD) than other Silicon-SPM-Probes.

Electric fields near the probe chip may lead to field evaporation which can blunt the tip apex of the probe tip. Therefore the NANOSENSORS™ are shipped in specially designed ESD-safe chip carriers.

NANOSENSORS™ recommends to their customers to take appropriate precautions to avoid tip damage due to electrostatic discharge when handling the probes. This can for example be done by using anti-electrostatic mats, wrist bands and tweezers.

SuperSharpSilicon™- Force Modulation Mode

NANOSENSORS™ SSS-FM AFM probes are designed for force modulation mode.

For enhanced resolution of nanostructures and microroughness we offer our SuperSharpSilicon™ AFM tip with unrivalled sharpness.

The FM type is offered for force modulation microscopy. The force constant of this AFM probe spans the gap between contact and non-contact mode and is specially tailored for the force modulation mode. The SSS-FM tip serves also as a basis for high resolution AFM tips with magnetic coatings (SSS-MFMR). Furthermore non-contact or tapping mode operation is possible with the FM tip but with reduced operation stability.

The AFM probe offers unique features:
  • guaranteed AFM tip radius of curvature < 5 nm
  • typical AFM tip radius of curvature of 2 nm
  • typical aspect ratio at 200 nm from tip apex in the order of 4:1
  • half cone angle at 200 nm from apex < 10°
  • monolithic material
  • highly doped to dissipate static charge
  • chemically inert
  • high mechanical Q-factor for high sensitivity
