Physical Sciences Building Rm B-91

The FEI CryoS/TEM is the result of NSF MRI award (1429155) and is the first monochromated, high-resolution cryo-S/TEM of its kind. This instrument is capable of imaging inorganic and organic materials at the nanoscale. It is equipped with a Field Emission Gun (X-FEG), a monochromator, probe corrector (STEM) and the availability of single and double tilt holders for room temperature and cryo work. The microscope is set up for data collection at 60, 80, 120, and 300 kV providing resolutions of up to 0.08 nm.

Duffield Hall 150

The UltraSTEM has a high-brightness cold field emitter and spherical aberration corrector integrated into its column, which nulls all axial aberrations up to fifth order. As a result, an angstrom-scale probe with 0.1 nA of current enables imaging with angstrom-level (0.1 nm) resolution. The electron optics can be quickly changed to produce a 2-3 angstrom probe with 1 nA or more of current for analytical purposes (electron energy loss spectroscopy). This instrument is notable for its high stability, and combined with the high-brightness source is well suited to mapping bonding changes at atomic-resolution using electron energy loss spectroscopy (EELS)
