Results in brief
Superlattices and proximity effects in 2D materials/molecules hybrid van der Waals heterostructures
The fabrication of materials with on-demand electronic, optical and magnetic properties lies at the heart of Materials Science. Efforts in the quest for materials by design have produced exquisite results in basic research and technology, which have impacted a number of research fields directly linked to applications (communications, information, mobility), ultimately revolutionizing everyday life. A strong connection exists between basic research in materials science and electronics, since the design of ultimately all electronic components relies on peculiar material capabilities. In this regard, the demonstration of new materials with tailored properties could improve current technology and inspire novel device concepts beyond conventional micro-electronics. In this search for materials by design, graphene and other two-dimensional materials (2DMs) offer a unique opportunity, since their reduced dimensionality makes it possible to controllably tune their intrinsic physical properties through ad-hoc modifications of their surface. Interfacing 2DMs with molecular thin films holds immense potential, since specific functional groups can be integrated in the molecular layer to provide programmable capabilities to 2DMs. SUPER2D aimed at combining 2D materials with molecular self-assembled monolayer, to obtain hybrid heterostructures with tunable properties. The project has exploited different, ad-hoc chosen molecular monolayers to introduce deterministic modifications in the intrinsic physical properties of 2DMs, with the ultimate goal of generating novel materials for next generation electronics. Special focused was dedicated to (i) silane-based functional molecules, with the goal of improving the performances of 2DM-based field effect transistors and manipulating the superconductive transition in superconductive 2DMs; (ii) organometallic molecules, with the goal of altering the magnetic properties of 2D materials. The ultimate objective of SUPER2D was the demonstration that 2DM/molecule interfaces represent an ideal experimental platform to design technologically relevant materials with programmable properties, fulfilling the central challenge of materials science.

Project objective
Van der Waals heterostructures, in which graphene and related 2D materials are mechanically superimposed in a stacked structure, represent a versatile platform to obtain materials with unique properties. These artificially-assembled materials will revolutionize a number of research fields directly linked to applications, such as information and communication, and ultimately everyday life. In this context, molecules are particularly attractive, since the almost-unlimited degrees of freedom in chemical design offer the possibility to confer ad-hoc functionalities to 2D materials, paving the way to novel and unexplored areas of physics and materials science.The researcher aims to impact this rising field by using metal-organic networks based on lanthanide ions and organic ligands self-assembled on the surface of 2D materials. In the resulting hybrid heterostructures, the metal organic network will determine a periodic modulation of the surface potential, due to charge transfer and molecular dipoles which occur at every node, forming a superlattice with unique electronic and optical properties. Moreover, the lanthanide ions, which possess high magnetic moment, will confer new magnetic properties to the 2D materials thanks to the proximity effect. The researcher proposes to investigate these electronic, optical and magnetic phenomena through a combination of different surface science techniques, which will provide a comprehensive understanding of the hybrid heterostructures.SUPER2D is a multidisciplinary project which combines the surface-science expertise of the Host institute (Centro Fisica Materiales) with the competences of the researcher in magnetism and molecule/2D materials interfaces. The overall mission of the fellowship is to train the researcher to become an independent scientist through the achievements of well-defined scientific objectives and the development of managerial and outreach skills, preparing him for a leading position in academia or industry.
