About

Hwang’s research has a well-balanced emphasis on fundamentals and applications. Using first-principles based atomistic modeling, his research group has focused on developing a deeper understanding of surface chemistry, solid-solid and solid-liquid interfaces, defects and chemical impurities, and charge carrier and phonon transport in nanostructured and disordered materials.  By incorporating the fundamental knowledge and data into larger scale simulations, they have also devoted efforts to addressing engineering problems encountered in the fabrication of energy and electronic devices.

Current focus areas include:

  • First-principles modeling of surface and interfacial reactions, defects and chemical impurities, charge carrier and phonon transport, and plasma-surface interactions in disordered composite/alloy nanomaterials
  • Computational design, evaluation and screening of nanostructured and nanocomposite materials systems for lithium-ion and sodium-ion batteries, electrochemical double-layer capacitors, and thermoelectric devices
  • Prediction and characterization of the atomic ordering and catalytic properties of multimetallic nanoparticles for hydrogen fuel cells and multicomponent oxide semiconductors for solar-powered water splitting
  • Fundamental understanding of the molecular mechanisms governing carbon dioxide capture and conversion
  • Multiscale modeling of semiconductor doping, electrochemical micromachining, and gas separation
