EQUIPMENTS

Transmission electron microscopy (FEI Tecnai F20)

  • Schottky field emission gun; acceleration voltage: 80–200 kV; resolution: 0.24 nm
  • specimen stage angle: ±30° (80° in nanotomographic mode)
  • Imaging in conventional and high-resolution modes with a magnification ranging from x50 to x1,000,000 (20 million on the CCD camera)
  • Scanning transmission electron microscopy (STEM) with bright-field detector (BF), annular dark field (ADF) and high-angle annular dark field (HAADF) modes
  • Local chemical analysis with an energy-dispersive X-ray spectrometer coupled to a nanometer probe
  • Energy-filtered imaging system (GIF) coupled to an electron energy loss spectrometer (EELS).

Scanning electron microscopy (FEI Nova NanoSEM 450)

  • Schottky field emission gun; beam acceleration voltage: 50 V – 30 KV; resolutions: 1 nm at 15 kV and 1.4 nm at 1 kV. High-resolution column with sufficient current for rapid EDS mappings and EBSD analyses at low and high magnification
  • “Low Vacuum” mode for the observation of non-conductive specimens
  • Secondary electron (SE) or backscatter electron (BSE) imaging studies using in-chamber or in-lens detectors with a useable magnification range from x35 to 600,000 (field width between 3.6 mm and 200 nm). Automated multi-field acquisition
  • Tunable-energy X-ray microanalysis with point, multi-point and mapping modes and qualitative and quantitative assessment
  • EBSD rapid acquisition system for crystal orientation mapping.
