Campus Shared Facilities
Comprehensive state-of-the-art instrumentation is available through the shared facilities listed below. Currently, we primarily use in situ bulk and thin film X-ray diffraction, in situ X-ray reflectometry, Rutherford backscattering spectrometry, Ellipsometry, Inductively coupled plasma mass spectrometry, Sputter deposition, Focused ion beam sample preparation, Transmission electron microscopy, and Scanning electron microscopy facilities. We also collaborate closely with groups accessing the campus’ computing resources.
Research at Other Sites
Through our affiliation with I2CNER, we conduct exchange visits to Kyushu University and/or collaborative research. I2CNER houses extensive instrumentation for the simulation, synthesis, and characterization of materials and devices for carbon-neutral energy technology. Recently we have used electron microscopes, scanning probe microscopes, angle-resolved X-ray photoelectron spectroscopy, bulk and thin film synthesis capabilities, and fuel/electrolysis cell test stations.
In addition to the above resources, synchrotron X-ray scattering and absorption studies are performed at the Advanced Photon Source of Argonne National Laboratory, a ~2 hour drive from campus.
