The FEI Titan 80-300 STEM is a scanning transmission electron microscope equipped with a field emission electron gun, a three-condenser lens system, a monochromator unit, and a Cs probe corrector (CEOS), a post-column energy filter system (Gatan Tridiem 865 ER) as well as a Gatan 2k slow scan CCD system. Characterised by a STEM resolution of 80 pm at 300 kV, the instrument was one of the first of a small number of sub-\u00e5ngstr\u00f6m resolution scanning transmission electron microscopes in the world when commissioned in 2006.<\/p>\n\n\n\n

Typical Applications and Limitations of Use<\/h2>\n\n\n\n

The FEI Titan 80-300 STEM allows a variety of advanced scanning transmission electron microscopy investigations to a wide range of materials. Techniques like electron energy loss spectroscopy (EELS), energy filtered transmission electron microscopy (EFTEM), high resolution scanning transmission electron microscopy (HRSTEM) with detectors for bright-field, annular dark-field, and high-angle annular dark field (HAADF) imaging, electron tomography (ET), and combinations of the previous techniques.<\/p>\n\n\n\n

The FEI Titan 80-300 STEM is not intended for the investigation of aqueous, contaminated, ferromagnetic or organic samples without further discussions with both of the instruments officers and the ER-C general management.<\/p>\n<\/div><\/div>\n\n\n\n

Sample Environment<\/h2>\n

Apart from the special case of the utilisation of dedicated cooling or heating stages, the FEI Titan 80-300 STEM will allow samples to be investigated either under room temperature or liquid nitrogen cooling conditions at a vacuum level of about 10\u20138<\/sup> mbar. Besides this standard setup, the sample environment can be adapted to various conditions, e.g. thermal treatment under vacuum or under gas atmosphere up to 1 bar using a MEMS-based closed-cell holder, or the application of external electric or magnetic fields to samples, making use of a wide portfolio of in situ<\/em> TEM holders available at the ER-C.<\/p>\n\n\n
