Material Measurement Laboratory /Materials Science and Engineering Division

Functional Nanostructured Materials Group

We develop measurement methods, models, data, and standards for the electrical, chemical, and magnetic properties of nanostructured inorganic materials, including metals and semiconductors, related to microstructure and processing. We are experts in nanostructure fabrication, in situ processing measurements, models for process control, and microscopy for improving the performance of these materials for energy, electronics, and other applications.

Group Competence

  • Deposition and evaporation of thin films and alloys
  • Electrodeposition of metals and alloys
  • Magnetic materials characterization
  • Growth of nanowires and creation of devices
    • Gallium-nitride and wide bandgap nanowires
    • Silicon and germanium nanowires
  • Measurements for evaluation of hydrogen in materials
