Welcome to Professor Zuo's research group
(This web site is being updated, please bear with us for broken links)
Structure plays a fundamental role in materials and their functions; whether
the function served is structural, electrical, magnetic, thermal, and optical or a
combination of these, properties of materials ultimately relate to their
structure. Our group specializes in the study of atomic structure and its
relationships to materials properties. We use a combination of nanodiffraction
techniques, aberration corrected electron microscopy, synthesis, and theory
to advance the study of atomic structure. For example, in the past few years,
we developed coherent electron diffraction and imaging techniques that have
enabled structure determination of individual carbon nanotubes and
nanoparticles.
We are currently funded for the study of defects in III-V semiconductor
superlattices, symmetry and local polarization in piezoelectric crystals,
structure of high Tc superconductors, supported nanoparticles and their
surfaces/interfaces.
A new research area we are developing is time-resolved electron
crystallography and dynamical transmission electron microscopy (TEM). In
this new initiative, we have constructed a time resolved electron diffraction
apparatus based on a 130 fs Ti-sapphire pulsed laser. More recently, we
received a NSF major instrumentation grant to develop a dynamical
environmental TEM.
