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
