Electronic properties of correlated two-dimensional materials

Two-dimensional (2D) atomic crystals, best exemplified by graphene, have emerged as a new class of material that may impact future science and technology. So far semiconducting 2D materials attracted most attention. Meanwhile, vast opportunities exists in correlated 2D materials: the reduced dimensionality may lead to novel properties that are vastly different from that in the bulk, and the exposed surface makes these materials highly tunable. In this talk I will discuss the emerging opportunities in correlated 2D materials. In particular, I will talk about two correlated 2D materials that we found particularly interesting – metallic 2D ferromagnet Fe₃GeTe₂ and monolayer Bi₂Sr₂CaCu₂O_8+δ. We explore their electronic properties while the doping and dimensionality of the 2D systems are modulated.
