    PhD Thesis: Electronic Structure of Molecularly Doped Two-Dimensional Materials from First Principles

    More than half a century ago, some great physicists theoretically proved that two dimensional crystals are unstable due to quantum fluctuations and could not exist. Half a century later, A. Geim and K. Novoselov isolated a few micrometers of perfect single-atom layers from graphite using a scotch tape. This new material, graphene, is a single layer of carbon atoms arranged in a honeycomb lattice. This 2D material has many promising properties with prospect in the field of nanoelectronics. However, to turn these attractive properties into useful applications, its electronic structure needs to be properly fine-tuned. One way to achieve this goal is by physisorbtion of molecular dopants. This work aims at a theoretical investigation of the electronic properties of graphene after interaction with organic conjugated molecules through a charge transfer mechanism.
