Instrumentation

The AF-SEM is an AFM which operates inside an electron microscope, allowing correlative SEM and AFM imaging.

This AFM provides standard AFM imaging, current measurements, surface potential (scanning Kelvin probe), magnetic and electric force microscopy.

This version is…

1. This microscope is placed inside an electromagnet which can reach field of 1 Tesla
2. Scanning range 5 microns xy, 700 nm z
3. Current-AFM capabilities with separate low and high amplifier ranges
4. Two-pass techniques including EFM and SKPM

The fast AFM is designated for measurements of dynamics and can function in air or in liquid. It was built in collaboration with the group of Georg Fantner at EPFL. In fast scanning mode, the tip is driven photothermally by a modulated laser. ultra-small cantilevers are employed…
