AFM and STM modules in one device.
-
Supports contact and tapping mode (closed loop control keeps the force (deflection of the beam which holds the tip) constant, which limits the contact forces to < 200 pN, i.e. a value far lower than the tapping forces of other devices – PeakForce tapping).
-
Enables measurements of elasticity modulus, adhesion, lateral force (LFM), spectroscopy and force modulation, electrochemical analysis, electric field and magnetic forces, surface potential, piezoelectric force; enables also nanolitography, …
Option to measure in liquid for biotechnical applications and measurements with heating/cooling of the samples, …
Imaging of measured data on 5’120 x 5’120 pixels.
-
Samples fixed to the support via a vacuum chuck can be up to few millimetres in size, with bidirectional positioning repeatability of 3 μm on a scanning area of up to 90 x 90 μm.

-
4 samples in a 100 x 100 mm sample holder with a scanning resolution of 0.1 μm and 1 μm accuracy; automatically controlled (closed loop based on incremental encoders). Measurement of elasticity modulus and hardness according to ISO 14577.
-
Enables LFM with a ≤ 2 mN resolution and max lateral force
≥ 250 mN. Low-force measurements enable obtaining surface topology after indentation.
