Noncontact Diamond Coated Conductive Probes DCP20 series, resonant frequency 260-630kHz, force constant 28-91N/m.
Coating Specification:
- Thickness of diamond coating is about 100 nm.
- Diamond coating is doped with nitrogen.
- Film resistivity: 0,5-1 Ohm*cm.
- Tip curvature radius after coating is about 100 nm.
- Recommended for electrical modes.
- Specially recommended for Oxidation Nanolithography*.
* We made a special "survival" test - almost 50 LAO Lithography images of Mona Lisa were obtained by using only one tip. It was not destroyed even after such a hard work. After 50 attempts it was still "alive".

LAO Nanolithography was made on Ti film in Semicontact mode by NSG20 probe with conductive diamond coating. NTEGRA Aura system. Scan size: 8x8µm. |
|
The thickness of lithography line was measured after the "survival" test.
It is about 22nm.

Probe specification
- Standard chip size: 1.6x3.6x0.4 mm.
- High cemically stable reflective Au coating (reflective property is 3 times better in comparison with uncoated cantilevers).
- Typical curvature radius of a tip: 100 nm.
- Tip height: 10 - 15 µm.
- Each chip has one TRIANGULAR spring.
- Compatible with the most commercial SPM devices.
- Silicon is doped by boron with the concentration about 5x1020 cm-3 to avoid electrostatic charges.
- Packaged in GelPak® boxes.
