Aberration-Corrected Scanning Transmission Electron Microscopy Facility

The facility's JEOL JEM2100F aberration-corrected scanning transmission electron microscope (STEM) characterizes the structure and composition of materials at atomic resolution.


  • Schottky field emission gun (FEG) with 1eV FWHM energy resolution
  • CEOS hexapole Cs corrector for the electron probe
  • 0.1nm resolution in HAADF mode
  • Fischione high angle annular darkfield detector (HAADF)
  • JEOL STEM bright field detector (BF)
  • Annular bright field (ABF) capability with the Fischione annular detector
  • Oxford Inca solid-state EDS detector
  • Gatan Tridiem Imaging Filter for energy filtered imaging and electron energy loss spectroscopy (EELS)
  • EELS and EDS spectrum imaging with Gatan Microscopy Suite
  • JEOL low background (Be) double-tilt holder for EDS
  • Protochips Aduro MEMs heating holder

TEM Performance

  • 0.19nm point resolution, 0.1nm information limit
  • Gatan Erlangshen wide angle CCD camera
