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.
