Characterization

Professor working in this area include:

The department of Mining and Materials Engineering is well equipped for the characterization of the microstructures of materials. The department hosts 5 scanning electron microscopes (SEMs), 4 x-ray diffractometers (XRDs), a three dimensional x-ray tomography systems, a state-of-the-art x-ray, and photo-electron-spectroscopy system (XPS). In addition, 5 transmission electron microscopes (TEMs) including a state-of-the-art TITAN Kryos and a field-emission Technai G20 are hosted within the FEMR. The department of Mining and Materials is well situated to perform materials characterization of materials with spatial resolution below 1 nm.

With all of these techniques available, the research group of Professor Gauvin works to develop quantitative methods to characterize the microstructures of materials with both electrons and photons. A key method is to simulate the trajectories of photons and electrons in materials using the Monte Carlo method. The research group of Professor Gauvin has developed many Monte Carlo programs, including CASINO, the best known software, to simulate electron trajectories within materials and is used in more than 10,000 users around the world.

Professor Gauvin’s research group recently acquired the highest performing SEM in the world, the Hitachi SU-8000. This cold field emitter has a spatial resolution of 0.5 nm with a maximum current of 40 nA. It has 7 electron detectors including a SDD EDS detector and an EBSD system. This microscope places our department at the leading edge in scanning electron microscopy.
