Facilities
Tecnai F30
The FEI Tecnai F30 is a scanning transmission electron microscope (STEM) that forms the centerpiece of the Electron Microscopy Core Facility. The microscope can be operated at the maximum accelerating voltage of 300 kV and is capable of atomic resolution imaging in both TEM and STEM modes. The microscope uses a Schottky field emission gun as its electron source, providing the highest current density and the smallest electron probe-size, which are critical for high spatial-resolution analysis using the scanning mode.The microscope is currently equipped with a high performance CCD camera with 4k x 4k resolution for image recording, an X-ray energy dispersive spectrometer (EDX) for compositional analysis, and STEM detectors for bright-field, annular dark-field, and high-angle annual dark-field (Z-contrast) imaging.
