Together with recent advances in exfoliation techniques, the discovery of graphene and other two-dimensional (2D) materials has laid the foundations for the manufacture of single layered sheets from any 3D layer. The 2D materials family includes a wide selection of compositions covering almost all of the periodic table elements. This result in a wide range of electronic properties including metals, semimetals, insulators and semiconductors with direct and indirect band gaps varying across the visible range from ultraviolet to infrarot. Therefore, they have the potential to play a crucial role in the future of nanoelectronics, optoelectronics and the assembly of modern ultra-flexible devices. We classify the 2D materials by their structure, composition and electronic properties. In this review we distinguish atomically thin materials (graphene, silicene, germanene, and its saturated forms; hexagonal boron nitride; silicon carbide), rare earth, Semimetals, metal transition chalcogenides and halides, and finally organic 2D synthetic materials, exemplified by 2D covalent organic frameworks. Our exhaustive data collection provided in this Atlas reveals the wide range of electronic properties, including band gaps and mobilities of electron. To cover their range of applications, peculiarities and drawbacks, the key points of the current analytical methods applied to 2D materials are discussed with special emphasis.
