RESEARCH AND INTERESTS
Our group focuses on the science underlying the synthesis and stability of advanced materials for applications in the areas of aerospace, catalysis, energy storage, and optoelectronics industries. We aim to develop detailed atomic-level understanding of the mass transport mechanisms, chemical reaction kinetics, and material thermodynamics controlling morphological, compositional, and structural evolution of materials. We use a variety of in situ (as well as ex situ) characterization tools such as variable-temperature scanning probe microscopy (STM/AFM), low-energy electron microscopy (LEEM), scanning/transmission electron microscopy (SEM/TEM), and X-ray diffraction (XRD) to investigate the kinetics of nucleation, growth, and thermochemical and mechanical stabilities of nanostructures.

Currently, we are interested in:
    • Growth, structural, and mechanical characterization of transition-metal carbide thin films and refractory high-entropy alloy compounds.
    • Growth and surface dynamics of 2D layered materials.
