Solid-State Chemistry and Photophysics of Hybrid Materials

Welcome to the Hybrid Materials Research Group website! Our research interest is to search for new organic-inorganic hybrid materials, to understand and control their properties, and to develop photonic and quantum devices from these materials. We use a variety of crystallographic and spectroscopic techniques to study these questions, including single crystal X-ray diffraction, electrical measurement, and time- and space-resolved optical spectroscopy. Please explore our website for more details.

Stabilizing metastable perovskite lattices in 2D

Our perspective paper entitled "Stabilization of Metastable Halide Perovskite Lattices in the 2D Limit" is published on Advanced Materials. We discuss an unprecedented stabilization of metastable perovskite lattices in the 2D limit (e.g., with a thickness down to a few unit cells) due to the dominance of surface effects. This stabilization enables new insights on the relationships between the crystal structures and optoelectronic and ferroelectric properties in halide perovskites.  View online

Resolving ferroelectric controversy in halide perovskites

Our review paper entitled " Stereochemical expression of ns2 electron pairs in metal halide perovskites" is published on Nature Review Chemistry.  We establish a unifying structure-property relationship among chemical composition, centro-symmetry breaking, lattice anharmonicity, ferroelectricity, dielectric screening, and Rashba effect in metal halide perovskites from the perspective of stereochemical expression of ns2 electron pairs on the group IV metal cations.
