Welcome to the Microscopy Group

The Microscopy and Microanalysis task involves operation and development of the SHaRE User Facility, applications to materials science, and research collaborations in the areas of:

1. analytical transmission electron microscopy: energy-dispersive X-ray spectroscopy, electron energy-loss spectroscopy, spectrum imaging, energy-filtered imaging, convergent beam electron diffraction, and high-resolution imaging;
2. atom-probe field-ion microscopy: atomic resolution imaging, high-resolution time-of-flight spectroscopy with single atom sensitivity, and three-dimensional atom probe techniques;
3. analytical scanning electron microscopy: secondary and backscattered imaging, energy- and wavelength-dispersive X-ray microanalysis, spectrum imaging, and electron backscattered pattern orientation measurements; and
4. mechanical property measurements with sub-micrometer lateral spatial resolution: nanoindentation experiments (hardness, modulus, viscoelasticity, creep, scratch, and fracture toughness) and atomic force microscopy.

Applications to materials science emphasize structure-property correlations in areas such as phase transformations, interfacial segregation, and irradiation phenomena for a wide range of materials including intermetallics, steels, structural ceramics, bulk metallic glasses, and thin films. A major part of this task involves providing facilities and expertise to university, industry, and government laboratory collaborators as part of the SHaRE User Program. This access includes the technical expertise of the task members in the collaborative research.
