Graphene, the one atom thick layer of carbon, has opened a fruitful field of research in condensed matter physics. Having reached a suitable understanding of graphene’s fundamental properties and applications, scientists are now turning their attention to structures composed of different 2D crystals. Significant effort has been put into the production of 2D crystals other than graphene, from thin insulators (like hexagonal boron nitride) to thin semiconductors (like molybdenum disulfide). Combination of these materials into structures named van der Waals heterostructures could allow for the engineering of tunable phenomena at the interface. In this talk, I will give an introduction to the Physics of graphene and I will describe two different quantum phenomena that can be observed in this two dimensional crystal:universal conductance fluctuations and superconducting proximity effect. I will present tunable phenomena that can be found at the interface between graphene and other materials like pentacene, a well-known organic semiconductor, and C60, the 0-dimensional version of graphene. To conclude, I will expose layered materials that rest unexplored and layered heterostructures that can lead us to exciting Physics.
