Van der Waals heterostructures based on 2D polymers

In this proposal we are planning to study van der Waals heterostructures consisting of combinations of different 2D polymers and graphene. Initial results of structures comprised of 2D polyimide and graphene have shown very interesting optoelectronic properties including a fast interlayer charge transfer. By performing GIWAXS experiments the crystal structures of the individual materials were visiualized, but further systematic study upon different fabrication conditions (e.g. degree of protonation) and material combinations will help to gain a better understanding of these novel material systems.
