Research Interests and achievement  
Updated on August 11, 2020
My research focused on exploring the condensed matter physics of multi-dimensional nanomaterials, such as semiconductor quantum dots and two-dimensional quantum materials. In recent work, we have demonstrated the ultralong spin/valley lifetime, symmetry-dictated optical selection rule/interlayer electronic coupling and layer-hybridized valley exciton. In addition to providing fundamental insights for moiré superlattice, these works further play an important role in developing quantum engineering of van der Waals heterostructures.
