Microanalysis Research Group (837.02)

Keana Scott, Group Leader

The Microanalysis Research Group performs research and development of microbeam analysis techniques for the chemical, morphological, and crystallographic characterization of matter down to nanometer spatial scales using excitation beams of electrons and x-rays to generate a variety of secondary signals that yield elemental and molecular information; studies fundamental measurements including x-ray and electron spectroscopies, computer aided imaging, and diffractometry to understand the basic chemistry and physics of microbeam sample interactions; develops improved methods of quantification as well as Standard Reference Materials and Data; and applies enhanced and multidisciplinary microanalysis and surface analysis techniques to diverse problems in material, semiconductor, optoelectronic, environmental, biological, and process technologies.

Surface and Interface Research Group (837.03)

Steven A. Buntin, Group Leader

The Surface and Interface Research Group conducts research towards the development of innovative metrologies and measurement protocols for micro/nano-scale heterosystems analysis.  Measurement techniques are used to determine sample composition as well as structural, electronic, and chemical properties of a wide variety of organic, inorganic and biomolecular systems where materials of interest are typically present as either micro/nano-scale features or mono/multi-layer films. Current research areas include 1) high/super-resolution and near-field microscopies, 2) nanoscale domain charge transfer dynamics, 3) linear and nonlinear laser-based spectroscopies and 4) nanoscale materials synthesis, fabrication and modification.

Analytical Microscopy Group (837.05)

Greg Gillen, Group Leader

The Analytical Microscopy Group conducts research by applying various microscopies to elucidate the chemical and structural properties of matter on dimensions of micrometers to nanometers where the major analytical techniques utilize excitation beams of ions, or ultraviolet to infrared photons, and detection of analytical signals from ions, electrons, or photons; applies scanning probe microscopies and nuclear track techniques; and researches the fundamental studies of the excitation process, quantification, standards development, instrumental improvements, data and image analyses, and applications of these techniques to problems in chemistry, materials science, semiconductor technology, biotechnology, and environmental science.
