Seminar of Prof. Humberto Terrones, Visiting Researcher of IMDEA Materials, “The Amazing world of 2D Materials”. September 19th, at noon in the Seminar Room.


We all are very familiar with graphene and carbon nanotubes and their extraordinary electronic and mechanical properties. Both materials are composed of sp2 carbon atoms; their structures look very similar locally but exhibit different properties due to the way their atoms are arranged in 3D space. In this talk, first: I will explain how graphene, carbon nanotubes and fullerenes can be seen under a unified concept, the concept of curvature, which can be applied to any other 2D material. Under this concept, I will explain how different structures can be proposed at different scales and levels of complexity. Second, I will show the richness of 2D semiconductors such as transition metal dichalcogenides (TMDs); I will focus on their amazing non-linear optical properties. Finally, the quantum single photon emission of a 2D insulating material known as hexagonal boron nitride (h-BN) will be explained and what the challenges are for its applications.
