Transmission electron microscopy

In the center we have two transmission electron microscopes (Spectra 300 and JEOL JEM-2100). Scanning transmission electron microscope Spectra 300 (Thermo Fisher Scientific) is the most modern research equipment of the last generation of transmission electron microscopes and enables comprehensive structural and chemical characterization of materials at the atomic and subatomic level.

Spectra 300 scanning transmission electron microscope

Spectra 300 (manual-Spectra 300)

• FEG electron source
• spherical aberration corrector
• monochromator
• observation with a parallel electron beam (TEM, HRTEM)
• electron diffraction (SAED, CBED, PED)
• qualitative and quantitative chemical analysis (EDXS, EELS)
• 4D STEM

Jeol JEM-2100 (manual-2100)

• JED 2300 EDS
• Gatan CCD camera ORIUS
• analytical holders (double tilt)
• cooling and heating holders (double tilt)
