FEI TF20 monochromated S/TEM

FEI TF20 monochromated S/TEM
  • Field emission gun (FEG)
  • Fully aligned for operation at 120kV and 200kV
  • 1 Å in TEM and 1.4 Å in STEM
  • GIF Tridium for EELS, energy filtered TEM elemental maps, low-loss studies (e.g. band gap analysis), chemical bonding information at nanometer resolution.
  • Sub-200meV energy resolution with monochromation
  • Electron tomography for determining 3-D structure from 2-D projections

Duffield Hall 150

200 kV field emission transmission electron microscope with monochromator. 1 Å in TEM and 1.4 Å in STEM. Equipped with a Gatan tridium spectrometer for electron energy loss spectroscopy spectra at high energy resolution <0.2 eV, optimized recording of energy filtered TEM elemental maps, EELS low-loss studies (e.g. band gap analysis), and chemical bonding information at nanometer resolution. The Tecnai is also able to do electron tomography, which produces 3-D structures from 2-D projections, by acquiring an image every 2 degrees at angles +/- 70 degrees. This is only possible using our tomography holder and specialized software.
