Electronic structure and electron dynamics in two-dimensional materials — •Philip Hofmann — Department of Physics and Astronomy, Aarhus University

Two-dimensional materials can be grown epitaxially and in high quality on different substrates, and this can be exploited to study their electronic structure and different many-body effects. In this talk I will review the growth and electronic properties of epitaxial graphene, bilayer graphene and single-layer MoS₂. Specifically, I will focus on the electronic structure of these materials as studied by angle-resolved photoemission spectroscopy. This technique does not only give access to the materials’ band structure but also to many-body effects such as the electron-electron and electron-phonon interaction. This is particularly so for the time-resolved variety of the technique in which the carrier dynamics can be followed in real time.
