Modification of 2D materials like graphene and MoS2 by molecular self-assembly: structure and function.

2Dfun aims at establishing 2D layers and heterogeneous layer stacks as basic building blocks of, and demonstrate them in functional  devices. To this end, 2Dfun will develop growth processes for 2D transition metal dichalcogenides (MX2) on graphene (with graphene coming from external resources within the Flagship) as well as high-k dielectric layers on MX2. Almost all work reported in literature in this area is based on natural MX2 material made by exfoliation, which however is not considered as a manufacturable route. An essential requirement for industrial applications is the availability of deposition techniques on large diameter (200-300mm) substrates with appropriate control over the process in terms of thickness, uniformity and material quality. Layer characterization as well as good control and understanding of the interfaces in such structures is key, and will help understanding device operation as well. Based on this high-volume manufacturing-compatible graphene/MX2/high-k platform, 2Dfun will make first functional hybrid MOSFET devices as demonstrator.
