Equipment

The AMCC has a range of microscopes available for your characterization needs. The TEM and SEM provide the ability to image objects from 5nm-5cm.  If the material is sensitive to damage from the electron beams or 3D visualization is desired, then our AFM can provide these details. The AMCC also houses X-ray diffractometers to analyze crystal structures and light scattering instruments to study size distribution.

Scanning Electron Microscope/Focused Ion Beam

The SCIOS Dual-Beam Scanning Electron Microscope/ Focused Ion Beam is a powerful research tool which allows for high resolution imaging as well as sample sectioning. Some of the features include:

  • Imaging Detectors: In-lens (T1, T2), CBS/ABS (Backscatter), ETD (Secondary), STEM w/ HAADF
  • FIB milling with Gallium LMIS
  • Platinum Deposition
  • Easy-Lift Needle Manipulator for TEM lammelas
  • EDX Elemental Analysis to indentify which elements are present in the sample
  • EBSD for grain orientation mapping (3D available)
  • Nability E-Beam Lithography

Scanning Electron Microscope (Low-Vac)

The FEI XL-30 provides high resolution imaging for both conductive and non-conductive samples (in Low-Vac mode). The XL-30 is equipted with an EDAX elemental analysis detector to provide compositional information of samples.

Transmission Electron Microscope

The CM-20 TEM provides sub-nanometer resolution for samples with a thickness less than 1 micron.

  • includes EDX Elemental Analysis
  • Orius CCD
  • Lab6 200Kv electron gun
  • Single and Double Tilt sample holders

Atomic Force Microscope

Atomic Force microscopy is an imaging and surface probing technique, used to determine sample roughness, suface imaging and force spectroscopy via nano-indentation. 3D imaging is possible for samples with sample height variations of less than 4 microns.
