are interested in photophysics in molecular, hybrid, and nano-scale semiconductors. A main research thrust is to establish new photophysical mechanisms that may be utilized to revolutionize solar energy
conversion or light emission. As examples, recent discoveries in our lab showed how an electron and a hole is bound by the Coulomb potential across an organic semiconductor interface, how
an exciton can split into two via the singlet fission process, and how a charge carrier in lead halide perovskite is protected as a large polaron
Our group is part of the NSF Materials Research Science and Engineeting Center (MRSEC), Center for Precision Assembly of Superstratic and Superatomic Solids. |
