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, Scanning probe microscopy, Rutherford backscattering spectrometry, Elastic recoil detection analysis, Nuclear reaction analysis, Ellipsometry, Inductively coupled plasma mass spectrometry, X-ray photoelectron spectroscopy, X-ray fluorescence spectroscopy, Sputter deposition, Focused ion beam sample preparation, Scanning transmission electron microscopy and spectroscopy, and Scanning electron microscopy facilities. We also collaborate closely with groups accessing the campus’ computing resources.
Research at Other Sites
Synchrotron X-ray scattering and absorption studies are performed at the Advanced Photon Source of Argonne National Laboratory, a ~2 hour drive from campus.
We have conducted further beamtimes and mail-in sample analysis with X-rays and neutrons at the Stanford Synchrotron Radiation Lightsource, ISIS Neutron and Muon Source (UK), and Oak Ridge National Laboratory.
We have conducted exchange visits to Kyushu University. I2CNER houses extensive instrumentation for the simulation, synthesis, and characterization of materials and devices for carbon-neutral energy technology.
