2D Meets 1 and 3D: Opportunities and Open Questions.

Since the discovery of graphene 2D materials have opened a new world of opportunities in a large variety of applications, ranging from electronics to energy harvesting. In this talk we walk through several examples in which 2D materials have enabled new functionality. We start by outlining the use of commercial graphene to integrate materials that otherwise would not exhibit any commercial latticematched epitaxial substrate. We then move by explaining how 2D materials can be integrated to 3D and 1D materials, forming heterostructures of hybrid dimensionality that involve highly heterogeneous materials. We explain how the functional properties of each part, strain and interface characteristics dictate the functionality of the whole and provide several examples.
