Transmission Electron Aberration-corrected Microscope Project

The project's main activity is design and application of a transmission electron microscope (TEM) with a spatial resolution below 0.05 nanometers, which is roughly half the size of an atom of hydrogen.

To minimize the mechanical vibrations, the microscope is located in a separate room within a sound-proof enclosure and is operated remotely.

The electron source is a Schottky type field emission gun with a relatively low energy spread of 0.8 eV at 300 keV.

The filter makes it possible to select electrons scattered by specific chemical elements and so identify individual atoms in the sample being studied.

A movie has been recorded inside the microscope showing hopping of individual carbon atoms around a hole punched in a graphene sheet.
