The XYZ Lab at Columbia University
Light-matter interaction, solar energy conversion, ultrafast spectroscopyGroup members | Publications
We are interested in the general problem of light-condensed matter interaction. 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 hybrid semiconductors can yield the highest possible quantum efficiency in light emission.
