The "HOWDI" research group: Van der Waals hetero-structures of low dimensionality "is both a national research group (GDR 2112) and an international coordination network (IRN" Graphene and co).
A huge scientific proliferation has emerged in recent years around man-made structures created by atomic-scale assembly of 2D materials into structures called van der Waals heterostructures (HvdW). This approach, which makes it possible to shape completely new physical properties by controlling assembly at the atomic scale, but with relatively light tools, inexpensive and accessible to a large number of laboratories, permeates all areas of physics: electronic transport in new regimes ranging from ballistics to saturation regime, from superconductivity to Mott insulators, optical with for example the appearance of topological effects in the excitonic signatures, with the ability to create almost perfect mirrors of thickness atomic, magnetic, thermal with new modes of heat dissipation thanks to the exploitation of near-field infrared modes in the structure… This ease of access and the wealth of new effects discovered explain the extraordinary popularity of this concept. to become a new paradigm in nanoscience.
We are organized into four thematic axes covering the different experimental approaches, but we obviously intend to do everything possible to promote exchanges between these approaches. Theoretical aspects are dealt with transversally. We break down this structuring into three axes through aspects of electronic transport and its interfaces (axis 2), optical, excitonic and photonic properties (axis 3) and properties related to spin and electronic correlations (axis 4).
- # axis 1: fabrication and advanced characterization of hetero-structures
- # axis 2: electronic transport and its interfaces
- # axis 3: optical, excitonic and photonic properties
- # axis 4: properties related to spin and electronic correlations
