CMEM Equipment

Shared equipment is available at UNM in various centers and departments and will be available for conducting the research described here. All of our shared equipment requires the user to get adequate training where individual use is allowed, or in some cases such as the XPS, students get to be in the lab but not operate the equipment hands-on. All user fees are borne by the faculty PI of the research group.

  • TEM/STEM Within the Earth and Planetary Sciences department at UNM, we have a JEOL 2010 purchased in 1992 and a JEOL 2010F TEM/STEM purchased in 2000.  Both microscopes are equipped with Oxford EDS systems, an INCA system on the 2010 and an AZtec system on the 2010F. The JEOL 2010F also has a Gatan imaging system (GIF 2000).
  • AC-STEM We have received a NSF MRI grant so the JEOL 2010F will be replaced with a probe aberration corrected TEM/STEM with dual EDS.
  • Confocal Microscope ZEISS LSM 510 META Laser Scanning Microscope to perform confocal fluorescence microscopy with 3 laser lines: Ar laser (458, 477, 488, and 514 nm) 30 mW; HeNe laser (543 nm) 1 mW; and HeNe laser (633 nm) 5 mW.
  • FEGSEM Hitachi S-5200 Nano SEM.  This SEM provides among the highest resolution available (1.7 nm at 1 kV and 0.5 nm at 30 kV).  Due to excellent facilities (e.g., vibration-isolation from vacuum pumps), the magnification ranges from x100 to x2M.  It is capable of energy dispersive spectroscopy (EDS) for elemental analysis using the Oxford AZtec system.
  • FEGSEM/FIB FEI Quanta 3D Dualbeam FEGSEM/FIB with EDAX Genesis EDS system and TSL EBSD.
  • Variable pressure SEM Tescan Vega 3 SEM with EDS system.
  • XPS The Kratos AXIS Ultra photoelectron spectrometer.  The XPS has both a monochromatic Al anode as well as a non-monochromatic Mg x-ray source.  The instrument contains a multi-sample autostage, for automated, overnight analysis.  This instrument currently has sub-micron spatial resolution, while spectra can be acquired from areas ranging from less than 15 microns to greater than several millimeters.  This instrument has the best spatial resolution of any commercially available photoelectron spectrometer.  The XPS is controlled by a Sun workstation that is networked to a PC for fast data transfer.  XPS data analysis also utilizes a number of multivariate analysis methods for evaluation of images and spectra.  The analysis utilizes a variety of software packages available, including Matlab, ENVI (The Environment for Visualizing Images), and Parafac.  Methods for importing AFM and XPS data into these programs have already been developed.
  • XRD Scintag Pad-V suitable for high resolution work, Rigaku Smart Lab powder diffractometer and Rigaku Rapid II micro x-ray diffractometer.
  • Electron Microprobe  JEOL 8200 Superprobe with five WDS spectrometers.
