Consortium

The Deep2D project gathers French experts in the fields of 2D materials, optical and electronic properties and transport, van der Waals epitaxy, and advanced characterization tools (STM/STS, PL/Raman, XPS/ARPES). This unique collaborative project will thus boost this fast-growing topic and put French research at the forefront in a very competitive international context. Moreover, in France, more and more research teams investigate the optical and electronic properties of 2D materials based on TI (Paris, Strasbourg, Grenoble, Nancy, Lyon, Toulouse…). Our consortium is composed of four very complementary partners, which bring all the necessary skills to the success of the project, including nanomaterial synthesis (PMC, IEMN, C2N and LSI), material characterization (PMC, C2N, IEMN), device fabrication (IEMN and C2N), electric and optoelectronic (PMC) transport measurements and DFT calculations (LSI). The four Partners share the interest for, and have strong experience in collaborative and multidisciplinary research as the one followed in DEEP2D project. They have already collaborated in different projects.

F. Sirotti is the coordinator of Deep2D.

The instrumentation is already available in the laboratories of the consortium. The funding is going to cover equipment to optimize the precision in sample positioning when exchanging samples between the different partners and device fabrication along with post-doctoral scientist circulating in the four laboratories, as well as a calculation node for theory partner. Here is a brief description of the four partners.

logopmc The Electrons Photons Surfaces (EPS) group of the Laboratoire de Physique de la Matière Condensée (PMC) is in charge of the characterization processes by polarized photoluminescence and STM and STL microscopy. The project scientific coordinator, Fausto Sirotti is associate researcher at SOLEIL Synchrotron and is expert in electron spectroscopy and surface science. He coordinates the tasks of the EPS group at LPMC and is the project coordinator. The members of the EPS group at PMC participates to the project sharing their long-standing scientific experience in 2D materials and physics of semiconductors. They also contribute with the technical skills developed in the most important experimental stations involved in the project: clean environment exfoliation, polarized micro photoluminescence, Scanning Tunnelling Microscopy and Scanning Tunnelling Electro Luminescence.

logo-C2NC2N hosts groups in the fields of material science, mesoscopic physics, optoelectronics and operates a national nano-fabrication facility (3000 m 2 clean-room). The Partner conducts (opto)electronic/spectroscopic studies of 2D materials. The MAT2D group (A. Ouerghi, J. Chaste, F. Oehler, D. Pierucci) focuses on fabrication of 2D materials, ARPES measurements, optoelectronic devices and opto-mechanical applications. In the project, MAT2D combines the expertise of the laboratory in atomically thin material synthesis, nanofabrication, (opto)electronic and spectroscopic characterization. Abdelkarim Ouerghi is the local coordinator.

logo_IEMNIEMN brings its expertise in material characterization (AFM, XPS, PL, Raman, FIB) and integration of thin processing and high frequency characterization. Its research nanofabrication facility includes a 1600 square meters ISO6 clean room equipped with state-of-the-art tools for micro and nanofabrication, including a gallium FIB. The electrical characterization facility of IEMN probe stations cover DC and high-frequency measurements (up to 1.1THz), including one cryogenic probe-station and a cryostat for magneto-transport experiments. Two groups of IEMN are involved in this project: EPIPHY and CARBON. The IEMN CARBON team performs the device fabrication and characterization. The IEMN CARBON team has a long experience in 2D-based RF devices, is expert in the development of 2D-based RF and opto-electronics devices. The EPIPHY team focuses on material characterization. It is expert in epitaxy of graphene (by CVD on metals and by MBE on SiC) and in material characterization of TMDs. Emiliano Pallecchi is the local coordinator.

lsi_logo_2018 The theoretical spectroscopy group at the Laboratoire des Solides Irradiés (LSI) is among the world leaders in the field of first principle calculations. It belongs to the European Theoretical Spectroscopy Facility (ETSF) which is a research network comprising 68 research teams across Europe and the United States. It develops theoretical and numerical approaches for the study of electronic and optical properties of materials, within ab initio framework (Density Functional Theory, Time Dependent - DFT, Many Body Perturbation Theory, GW approximation), which is state-of-the-art formalism. Part of its activity is dedicated to surface properties (silicon, eventually functionalized) and 2D material (graphene, MoS2, hBN, thin slab of silicon). Christine Giorgetti is the local coordinator.
