- The Tecnai G2 F30 field emission gun transmission electron microscope combines all imaging, diffraction, and analytical techniques at high spatial resolution and detection efficiency. The high-brightness, high-coherency gun allows large electron probe currents to be focused onto nanometer-sized areas of the specimen.
- Application-specific modes include: High-resolution bright- and dark-field imaging; TEM microprobe and nanoprobe analysis; small-probe convergent beam; STEM imaging; and hollow cone and high-angle annular dark-field imaging modes.
- Accelerating voltage range of 50 to 300 kV.
- Magnifications up to >1 million times.
- Point resolution: 0.20 nm; Information limit: 0.14 nm; HAADF STEM resolution: 0.19 nm.
- Maximum specimen tilt: 40°.
- Drift rate: <1 nm / min.
- Specimen holders: Single- and double-tilt holders; Protochips Aduro heating holder.
- Energy-dispersive X-ray spectrometer: EDAX rTEM with an ultrathin window allows detection of elements from boron to uranium.
- Electron energy loss spectrometer: Gatan Enfina spectrometer allows detection and chemical analysis of elements as light as lithium with an energy resolution of 0.35 eV (FWHM).
Sample applications include:
- Composition analysis structure of grain boundaries in ceramics
- Lattice imaging of defects semi-conductor epitaxy, growth, and defects in analysis and metrology
- Magnetic films on chromium
- Identification of precipitates in materials
