In just a few years, graphene has become one of the most actively studied subjects in condensed matter physics and nanotechnology, owing to a host of appealing properties and potential applications of graphene. Furthermore, it is now appreciated that graphene is just one member of a much larger family of 2D atomic layered crystals, which is rapidly emerging as an exciting new field of research promising even richer physics and applications beyond those of graphene. These van der Waals coupled 2D materials allow much easier access of novel surface and edge physics, and can also be used as "building blocks" to form almost infinite possibilities of novel artificial materials and structures that cannot be found naturally nor grown by traditional methods. In this talk, I will describe several recent experiments on graphene, topological insulators and other 2D materials and their heterostructures, and discuss the potential for such studies to bring new insights on quantum Hall effects, spintronics, and even superconductivity.
