In this thesis, the growth of 2D materials, in particular graphene and FeO2 on crystalline supports, is studied by a multitude of surface-sensitive techniques. The mechanisms of graphene growth in ultra-high vacuum and high Ar pressure are explored, and a simple device for the manufacturing of high-quality, monocrystalline graphene on SiC is described. The electronic and chemical properties of B and N dopants on graphene are characterized by means of STM/AFM with CO-functionalized tips and supported by DFT calculations. The chemical interaction of a probe molecule (FePc) with doped graphene is also investigated. The long-standing controversy of the so-called "biphase" reconstruction of α - Fe2O3(0001) is resolved by the discovery of a complete FeO2 overlayer in this phase. The structure of this overlayer is investigated by means of STM, LEEM and DFT calculations. A thorough description of the routes to obtain single phases over the whole surface of α - Fe2O3(0001) is provided.
