2D materials are of interest because they display interesting and peculiar electronic properties. The discovery of grahpene has impulsed the synthesis of novel 2D materials (mono-atomically flat sheet of an element, transition metal dichalcogenides, topological insulators...).In the first part, this talk will describe the synthesis and the physical characterizations of two novel bidimensional materials: silicene and nanocrystal superlattices (atoms are replaced by semiconductor nanocrystals).In both cases, transport measurements were systematically investigated with the help of a state-of-the-art 4-probes Scanning Tunneling Microscope (STM).In the second part, we will look at the application of a 2D material (graphene) for the self-organization of magnetic nanoparticles of FePt for ultra-high density storage applications. The nanoparticle morphology and organization have been investigated using Grazing Incidence Small Angle X-ray Scattering (GISAXS), while their magnetic properties have been studied by X-ray Magnetic Circular Dichroïsm (XMCD).
