Carbon nanomembranes as a platform for engineering of functional 2D materials — •Andrey Turchanin — Institute of Physical Chemistry, Friedrich Schiller University Jena, 07743 Jena, Germany — Jena Center for Soft Matter (JCSM)

Carbon nanomembranes (CNMs) are ultrathin molecular sheets (~1 nm) which can be generated via electron, ion or photon induced crosslinking of aromatic self-assembled monolayers. Similar to graphene or other atomically thin 2D materials (hBN, MoS2, etc.) they possess mechanical integrity and therefore can be transferred from their original substrates onto new substrates, fabricated as suspended sheets or stacked into van der Waals heterostructures with a precise control over their thickness. Their physical and chemical properties can be tuned via an appropriate choice of molecular precursors or their post modification, providing a flexible platform for engineering of functional 2D materials. In this talk, some examples of these materials and their applications in devices will be presented. These examples include: (i) biofunctional and photoactive CNMs; (ii) gratings for matter-wave interferometry; (iii) growth of graphene with adjusted electronic and structural properties; (iv) chemical functionalization of graphene and MoS2 field-effect devices; (v) novel hybrid 0D/2D layered materials.
