Kick-off meeting of GDR HOWDI

Wednesday afternoon, March 24th, 2021
Due to the ongoing sanitary crisis, it is still impossible to gather the community of our new GDR "HOWDI" physically. However, we will celebrate this new start with a short virtual kick-off meeting, on Wed. March 24, 2021 afternoon. The program of the meeting will be announced shortly; it will consist of a general presentation of the thematic lines of the new GDR, a series of selected focused scientific talks and an open discussion about your needs and wishes for the future of the GDR.

2021-2025: our network focuses on van der Waals heterostructures, becoming "GDR HOWDI"

HOWDI: HeterOstructures of van der Waals materials with low DImensionality
For the coming five years, our network (GDR after "groupement de recherche") will cover the study of van der Waals heterostructures, following four main directions:
- synthesis, nanofabrication, caracterisations
- electronic transport and its relationship with other fields
- optics, excitonics, photonics
- magnetism, spintronics, electronic correlations
