Field Emission Scanning Electron Microscope (FESEM)

Model Hitach SU-70, variable pressure FESEM with EDX and nanolitography.
The Hitachi SU-70 Analytical Field Emission SEM combines the field proven stability, high current and brightness of the Schottky electron source with the ultra-high resolution of 1 nm. The large specimen stage and analytical chamber accommodate a wide variety of analytical instrumentation such as EDS*, WDS*, EBSP*, CL*, STEM, and e-Beam Lithography techniques optimized for simultaneous analysis.


Poza FESEM

Scanning Probe Microscope (AFM/MFM)

It is based on the detection of the interactions forces (electric or magnetic) between a probe and the sample surface (conducting, insulator or magnetic samples). A tiny tip fixed at the end of a flexible cantilever is scanned in a raster pattern over the surface. The tip-sample interaction leads to the cantilever deflexion which is monitored using a laser beam reflected from the top surface of the cantilever. The beam is reflected towards an array of photodiodes. A feedback control assures a tip-sample interaction constant during the displacement. Our AFM (NT-MDT Solver Pro-M) is installed on a vibration isolation table and can be operate in contact, tapping and non-contact modes.


Poza AFM

The handling of nano-object (indentation, local anodic oxidation, etc.) is facilitated by the Nanolithography software.
This device offers applications in various fields (physics, chemistry, biology). It is a tool that can be used for the characterization of roughness or to discriminate between different types of materials. The mapping of the magnetic field (MFM) could be also realized.
