Electron Spectroscopy Group: Facilities
The electron spectroscopy group conducts research in two main areas, Fourier transform infrared spectroscopy, and angle resolved photoemission spectroscopy.
ARPES
Angle resolved photoemission spectroscopy (ARPES) is performed on a Scienta SES-2002, shown below at beamline U13UB (sans aluminum foil). The current maximum energy resolution of this state-of-the-art spectrometer is about 1 meV.
Infrared Spectroscopy
The majority of infrared spectroscopy is performed on one of two instruments. The Bruker IFS 113v is a venerable Genzel-type interferometer that is used primarily as an off-line spectrometer for routine measurements below 1 eV with a maximum achievable resolution of 0.03 cm-1. The Bruker IFS 66v/S is a Michelson-type FTIR interferometer that can perform measurements from about 3 meV to almost 4 eV with a resolution of 0.1 cm-1. We are currently pushing the high-frequency response of this instrument. Synchrotron-based measurements are preformed at U12IR (currently under development).
In addition to the two main types of spectrometers described above, facilities also exist within the department of material synthesis and characterization. However, these facilities are not available for general use and may only be accessed internally with the approval of the appropriate research group.
