SPARK 70 Pt Conductive AFM Probes
Robust, high-resolution probes for electrical characterization. Rigorous inspection of every probe means each one performs as you expect.
Pack of 10 conductive AFM probes with platinum coating on both sides, suitable for electrical characterization in AC modes (non-contact/tapping).
40 nm platinum coating with a 5nm titanium adhesion layer on both sides of the probe and a tip radius of less than 30 nm.
