Pt Coated probe 镀白金导电探针(AFM 探针)

Typical radius of uncoated tip : 8 nm
Resulting tip radius with the coating : < 30 nm
Full tip cone angle* : 40°
Total tip height : 12 - 18 µm
Probe material : n-type silicon
Tip coating : Platinum
Detector coating : Platinum

The Cr-Au coating is formed as a 30 nm Au film with a 20 nm Cr sublayer, which is deposited for better adhesion of Au. The coating is formed on both tipside and backside of the cantilever. The coating may cause cantilever bending within 3°.

APPLICATION

The gold coating is inert, which makes these probes applicable for many experiments in biology and chemistry. Gold coated probes are also used in certain electrical applications.
