Research Description

Advanced microscopy techniques developed in the past two decades have enabled studies of the structure of materials with atomic level
detail. Research in the Paulson group is focused on combining these powerful microscopies with material characterization techniques to
study the relation between properties and atomic structure.  We have developed novel fabrication techniques that allow us to combine
high-resolution transmission electron microscopy and diffraction with electrical characterization of carbon nanotube samples.  We have also
fabricated torsional oscillator devices in similar geometries to probe mechanical interactions between concentric nanotubes.  Such devices
will allow us to understand the importance of atomic structure on interface properties at the nanometer scale.
