Description
ETALON is a new series of excellent composite AFM probes.
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.

Coating is stable at +/- 10 Volts and continues operating after long intensive use.
