RESEARCH DESCRIPTION
The focus of our group is to develop the
science underlying the controlled synthesis of advanced materials for
applications in the areas of energy storage, optoelectronics,
thermoelectrics, and hard coatings. Our group believes that the progress
in nanoscience and technology can only be achieved through a detailed
atomic-level understanding of the kinetic processes, mass transport
mechanisms, chemical reaction paths, and material thermodynamics
influencing nanoscale functionality. To this purpose, we use a wide
variety of in-situ (as well as ex-situ)
characterization tools such as variable temperature scanning probe
microscopy (VT-SPM), photoemission electron microscopy (PEEM), low-energy
electron microscopy (LEEM), scanning electron microscopy (SEM),
transmission electron microscopy (TEM), and X-ray diffraction (XRD) to
investigate the growth and stability of nanostructures, surface and bulk
structure, and kinetics of nanoscale pattern formation.
Currently, our group is interested in:
·
In-situ growth studies of
semiconducting nanowires
· Kinetics
of facetting on catalytic surfaces
· Thin
film physics of organic semiconductors & hydrogen storage materials
