Self-assembly and heterostructures

Ordering nanoparticles of different compositions, sizes, shapes can significantly increase materials complexity and give rise to new properties. We explore new ways to design nanocomposite materials with controlled heterogeneities. This research axis leads us to question the underlying mechanisms at play in during the formation of nano-objects.
