Quantitative Nanostructure Characterization Group

The projects within the group are highly interconnected to cover metrology and standards development as well as pursue novel device concepts, particularly for 2D materials, magnetic nanomaterials and group III-nitride semiconductors. We maintain active collaborations with other groups at NIST and with universities and companies from around the world.

Nanostructures are a critical component of innovations in high performance computing, electronics, energy conservation, renewable energy, biomedical research, and health care. We develop and demonstrate metrology techniques to address nanoscale measurement challenges. These techniques include scanning microwave microscopy, atom probe tomography, transmission electron microscopy, Raman spectroscopy, and time-resolved photoluminescence. Our goal is to push these methods beyond comparative measurements by evaluating absolute uncertainties with cross-method comparisons and calibration techniques that reveal systematic errors. We synthesize semiconductor nanostructures to serve both as test structures for measurement techniques and as building blocks for novel metrology tools.
