| Abstract Scope |
One exciting aspect of two-dimensional (2D) materials is that their nearly atomically thin layers can be stacked in various ways to obtain polymorphs and heterostructures with emergent optical and electronic properties. This can be achieved either by altering synthetic conditions to favor multiple polymorphs or defect structures, or by growing dissimilar materials on top of each other. When dissimilar materials are stacked, their atomic orientations, registry, and even chemistry can be influenced by the layers below them that are grown first. This leads to exciting opportunities to tune their properties. Here, we will examine several examples of atomic stacking in 2D materials. Examples will include NbSe2/BiSe/Bi2Se3, WTe2, polymorphs of GaSe, etc. We will also highlight strategies for understanding the precise stacking and defect structures using advanced data analysis, including machine learning. |
