The Nobel-prize winning discovery of graphene in 2004 jump-started a new research area of two-dimensional (2D) materials.1 The decrease in material's thickness to a single atom or few-atom layer can dramatically impact its electronic, optical, and magnetic properties. Over the last decade, a range of inorganic compounds have been reduced to atomically thin structures, the most notable being transition metal dichalcogenides, chromium thiophosphate, and black phosphorus.2,3

In contrast to graphene, the few-layer black phosphorus, known as phosphorene, exhibits finite band gap that can be tuned depending on the thickness of the material. The semiconducting nature of phosphorene allows separation and manipulation of excitons generated by thermal perturbation or photoexcitation. Such properties make this material especially appealing for the development of revolutionary 2D electronic devices.

This project focuses on the discovery of other materials that can be reduced to the 2D and 1D realm. We are particularly interested in materials whose electronic, optical, and magnetic properties manipulated the reduction to a few unit cell thickness. The 2D and 1D materials produced in our labs are study by means of magnetic property measurement system (MPMS), physical property measurement system (PPMS), Raman spectroscopy, atomic force microscopy (AFM), etc.
