Punte per non-contatto conduttive ricoperte di diamante della serie DCP20, frequenza di risonanza 260-630kHz, costante di forza 28-91N/m. Punte stabili, non-dintruttive, resistenti all'usura con un rivestimento conduttivo di diamante che vi permette di usarle molto a lungo. Le punte ideali per la nanolitografia AFM a ossidazione.

DCP20

Coating Specification:

• Thickness of diamond coating is about 70nm.
• Diamond coating is doped with nitrogen.
• Film resistivity: 0,5-1 Ohm*cm
• Tip curvature radius after coating is 50-70nm.
• 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".

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: 10 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.

GelPak® is a registered trade mark of Vichem Corporation.
