Departmental Facilities (Equipment)


  • A general purpose JOEL-2300 scanning electron microscope (SEM) with a Link Systems energy dispersive x-ray (EDX) analysis system for elemental identification.

  • An ultra high vacuum surface science facility that includes; a VG CLAM-2 X-ray photoelectron spectrometer (XPS); a scanning electron gun for scanning Auger microprobe (SAM) analysis in conjunction with the CLAM-2 spectrometer; electron gun and optics for low energy electron diffraction (LEED); a residual gas analyzer; a photo emission electron microscope (PEEM); a supersonic molecular beam source. The vacuum in this system is maintained by ion pumps and samples may be transferred from atmosphere via a turbo molecular pumped load lock, which may also be used for sample preparation.

  • A ultra high vacuum low energy electron microscope (LEEM) that also includes a deuterium lamp for PEEM, an SVT Associates atomic nitrogen source and a residual gas analyzer.

  • A high resolution electron energy loss spectroscopy (HREELS) system with Leybold EL-22 HREELS optics, a low energy electron diffraction (LEED) system, residual gas analyzer and manipulator for in situ tribology research. This is all housed in an ion pumped ultra high vacuum system.

  • An ambient atmosphere NanoScope II scanning tunneling microscope (STM) and associated electronics.

  • A Rigaku DIMAX-B x-ray powder diffractometer with a theta-theta goniometer and computer automated data acquisition and analysis system.

  • A EGG PARC 4500 computer controlled vibrating sample magnetometer with duplex refrigerator for magnetic moment measurements from 15 K to room temperature in fields up to 0.2 T.

  • A duplex refrigerator-based heat capacity apparatus for computer atutomated measurements from 20 K and up.

  • Computer automated duplex refrigerator-based resistance measurement apparatus from 15 K and up.

  • Controlled atmosphere glove box for handling air-sensitive materials; computer-controlled dual-zone furnaces for materials preparation.

  • He evaporator for measurements of thermal and transport properties to 0.3 K in superconducting magnetic fields up to 5 T.

  • Through ongoing collaborations, we have the use of thermal and cold neutron scattering facilities at NIST, ORNL, and ILL at Grenoble. We also make use of intense photon sources at the Wisconsin Synchrotron, for the analysis of materials properties.

  • An ultra high vacuum sputter deposition system for the growth of epitaxial multilayers thin films.

  • One of the beam lines from the 4.5 MV tandem Van de Graaff accelerator on campus leads to the W. M. Keck Thin Film Analysis Facility--an integrated ultra high vacuum (UHV) thin film deposition and characterization facility. Permits Rutherford Backscattering Spectroscopy (RBS), Nuclear Reaction Analysis (NRA), Elastic Recoil Spectroscopy (ERS) and Proton-Induced X-Ray Emission (PIXE) under UHV conditions.
