Since the discovery of graphene, the field of research in extremely thin materials, so-called 2D materials, has increased exponentially. 2D materials have a large surface area in relation to their volume or weight. This gives rise to a range of physical phenomena and distinctive properties, such as good conductivity, high strength, and heat resistance. Researchers at Linköping University, Sweden, have now developed a method that enables the synthesis of hundreds of new 2D materials.
