Biography
Xu Du is a Professor at Stony Brook University. He received his PhD from University of Florida in 2004. He was then a postdoc associate at Rutgers University from 2004-2009, where he did research on the charge transport properties of graphene. He is continuing his research on two-dimensional materials in his quantum transport lab at Stony Brook.

Research Statement
Scientific breakthroughs often benefit from the discoveries of novel materials. This applies to two-dimensional (2d) materials study which flourished over the past decades, starting from graphene , then expanding to a wide variety of other layered materials and more recently, heterostructures. The ability to extract 2d atomic crystals from their layered “mother” materials allows study of their properties during a 3D-to-2D transition as well as the investigation of the proof-of-principle devices for applications. The freedom of reassembling some these crystals to form heterostructures enable the study of some of the long-standing condensed matter physics problems such as strongly correlated electrons in solids. All these developments and possibilities drastically broadens the research scope of 2d physics.

My research interest lies on understanding the quantum charge transport phenomena in 2d atomic crystals. This includes study of their intrinsic magnetotransport properties, the impact of extrinsic perturbations (such as disorder and mechanical strain) on their electronic properties, and hybrid devices combining two-dimensional atomic crystals and other material systems. Most recently, I invested significant effort in creating novel quantum systems and meta-materials based on the electron gas in some of the 2d materials.
