Research

  1. Computational materials science
    • Materials modeling based on Density Functional Theory and Machine Learning to explore process-structure-property-performance relationships
    • Bottom-up approaches bridged by crystallographic symmetry, statistical mechanics, and nucleation theory: from first-principles to thermodynamics/kinetics
    • Development of computational methodology and its implementation in automation software
    •  Leveraging the numerical methods of crystallography, machine learning, and graph theory into computational materials design
  2. Atomistic understanding of spontaneous formation of nanostructure morphology
    • Understanding the formation principle of atomic structures depending on process conditions
    • Predicting the anisotropic interaction between solid surfaces and their environments
    • Elucidating the peculiar unidirectional growth morphology of dendrite and nanowires
  3. Material implications for device characteristics
    • Polar materials: III-V and II-VI for optoelectronics, (Hf,Zr)O2 for ferroelectrics, SrTiO3 for high-k and resistance-switching materials
    • SnO for p-type oxide semiconductors
    • Solid electrolyte interphase (SEI) and Li dendrite formed by Anode/electrolyte interface reactions in Li metal batteries
