High Accuracy High Resonance frequency non-contact AFM probes HA_FM series with stable and wear-resistant long lifetime W2C conductive coating.
The main advantages of W2C coated probes are:
  • Hard coating which stays stable at applied high voltages and flowing currents at the contact point ‘tip-sample’ which cannot be received with standard metal coated probes (Fig.1-3);
  • High conductivity (close to metal conductivity);
  • Typical curvature radius less than 35nm;
  • W2C+ was modified by volume doping with anticorrosion elements thus providing long-term performance in high humidity conditions.


Experiments, carried out in december 2015 by NT-MDT Spectrum Instruments, approved great stability of W2C+ coated probes under high voltage, current and tip-sample pressure. AFM cantilevers showed to be able measure current of several mkA during the whole scan without any degradation. The same excellent performance continued after 100 I-V curves by the range +/- 10V.
