Welcome to the Liu Research group!

Our research focuses on low-dimensional materials for their novel optoelectronic properties and potential applications.  In particular, we are interested in using TEM imaging and spectroscopy in combination with optical spectroscopies to understand excitons, polaritons and optically active quantum defects in 2D materials.
