Maria uses confinement heteroepitaxy to make new heterostructures that consist of monolayer graphene and 2D Sn. She characterizes these samples with ARPES, XPS, and LEED and compares the measured electronic structure with DFT calculations looking for indications of hybridization between the layers. She investigates these heterostructures with tr-ARPES looking for ultrafast charge transfer and other proximity-induced non-equilibrium effects.

Johannes investigates the microscopic scattering channels that are responsible for ultrafast charge transfer in WS2/graphene heterostructures. He focuses on the role of defects and the twist angle between the layers.

Franziska uses confinement heteroepitaxy to make new heterostructures that consist of monolayer graphene and another 2D material such as 2D Ag, 2D Yb, or 2D Sn. She then uses tr-ARPES to investigate the non-equilibrium carrier dynamics of these heterostructures looking for ultrafast charge transfer and other proximity-induced non-equilibrium effects.
