Why 2D materials: When we reduce a material into a single or few layers of atoms, the electrons and holes are spatially strongly confined in the same order as the exciton radius. Hereby, this quantum confinement leads to substantially modified properties of the bulk material, most commonly expressed as a blue shift of the spectra. The technological relevancy is immense, providing new ground for flexible electronics, light emitting and detecting devices as well as high-capacity batteries. Yet, there are multiple challenges we face to describe the 2D materials synthesized with scalable methods. The materials show defects, complex layering and stacking, of which the electronic structure is largely unexplored. Moreover, a clever design of heterostructures can provide even more exotic properties. To fill this gap, we use ab initio methods to simulate the electronic system of the thin materials from the ground up and gain insight into the exciting properties of the widespread 2D materials family.
