Graphene Revisited by Many-Body Theory: From Orbital Mapping to its Impact as a Substrate
Despite the numberless amount of investigations on graphene performed over the last years, this material still offers a variety of fascinating aspects to explore, in particular in view of its excitations. Combining density-functional theory with many-body perturbation theory provides a powerful framework for this purpose. Based on this methodology, I will address the following questions: Can we “see” orbitals in an electron microscope, and what kinds of images are to be expected? Can we introduce novel spectral features by stacking 2D materials? How are first- and second-order Raman spectra are affected by strain, that may be induced by an underlying substrate? How does graphene as a substrate, in turn, impact the photo-switching behavior of molecules?
