We are a multidisciplinary research group. Our aim is to characterize, understand and control light-matter interactions, with a focus on sensing, engineering and exploiting novel optoelectronic properties emerging from nanostructures and interfaces. This offers unprecedented opportunities for developing innovative material and device functionalities that rely on dynamic, local manipulation of single photons and charge carriers. We gain our knowledge by correlating spatially-dependent physical properties (e.g. electronic structure, excitonic interactions) with chemical information (e.g. molecular composition, reaction rates and dynamics) and morphological structure (e.g. strain, phase).
This work is enabled by new sensing and spectroscopic methods that we are continuously developing. Our approaches are typically grounded in (nano)optical, scan-probe, and single-molecule imaging techniques, which provide unique access to behavior at relevant length and time scales in real environments encountered in energy and biological applications.
A new article titled "Deconvoluting the Photonic and Electronic Response of 2D Materials: The Case of MoS2" came out in Scientific Reports, on our collaborative work with the Robinson group at Penn State.
Congrats to first author Ned Zhang!
Well done, Tom!
