Material dimensionality plays a crucial role in determining material physical properties. Research in graphene and the methodology of preparing ultrathin layers has led to the exploration of other 2D materials. In particular, single layers of transition metal dichalcogenides (TMDs) with lamellar structures similar to those of graphite have drawn significant attention because of their tunable bandgaps. In exploring and developing these emerging materials, nanoscale characterization becomes ever more important.  In particular, high resolution electron microscopy-based techniques now are capable of analyzing these materials and devices with better than 0.1 nm resolution.  In this talk, I will present an overview of current TEM-based state-of-the-art capabilities enabling comprehensive analysis of nanostructures. Examples will include various 2D materials from Graphene to TMDs, and 2D hetero-structures. Unique in-situ TEM-based techniques enabling comprehensive analysis will also be presented.
