The Tecnai F30 (FEI company) is a versatile high resolution Transmission Electron Microscope. It can work in TEM or STEM (Scanning-Transmission) modes. It is equipped with all the analytical techniques to obtain morphology, structure and composition information with atomic resolution.
The working voltages in this microscope are 200 and 300 kV.
 

What can be done with it?

Image (0.15nm resolution):

  • Size and morphology information  (TEM)
  • Crystalline Structure (Electron Diffraction & High Resolution TEM)
  • Composition: Scanning-Transmission Imaging with a High Angle Annular Dark Field detector (STEM-HAADF). The contrast in the image depends on the atomic number (Z-contrast). Energy Filtered TEM (EFTEM) yields information about a specific element.
  • 3D reconstruction: Electron tomography.

 

Chemical Analysis:

  • X-Ray (EDS) and Electron Energy Loss Spectroscopies (EELS).
  • Combined with the STEM mode: chemical composition with spatial resolution: composition maps and profiles.

 

Vector Field analysis:

  • Magnetic domain studies: Lorentz Microscopy
  • Stress and strain studies by HRTEM imaging.

 

In-Situ physical properties measurements:

  • Changes of crystalline phase (Electron diffraction).
  • Defect structure by bright field/dark field imaging (BF/DF) and Weak Beam imaging (WBDF).

 

Technical specifications

This 300 kV Field Emission Gun (FEG) TEM is fitted with a SuperTwin® lens allowing a point resolution of 1.9 Å. This TEM can work in TEM and STEM mode. For Z-contrast imaging in STEM mode, it is fitted with a High-Angle Annular Dark Field (HAADF) detector. This TEM is equipped for spectroscopy experiments performed either in EDS (X-Ray Microanalysis) or in Electron Energy Loss spectroscopy (EELS). For the latter, it is fitted with the “Tridiem” Gatan Energy Filter (GIF). This EELS set-up allows Energy Filtered TEM (EFTEM) images to be recorded as well as line spectra or spectrum imaging experiments to be performed. A 2k x 2k Ultrascan CCD camera (Gatan) is located before the GIF for TEM imaging.
 
In addition to these capabilities the F30 TEM is also fitted with a Lorentz lens which permit the study of magnetic materials in an environment free of magnetic field (for magnetic domain imaging). Furthermore, the F30 allows tomography experiments to be performed both in TEM and STEM mode using a dedicated single tilt holder (+/- 70°) from Fischione.
