Introduction of the Research Group
The momentum research group investigates the tuning of twisted van der Waals heterostructures. In such structures, e.g. for two graphene layers placed on top of each other under a magic angle topological, correlated phases from superconducting to Chern insulating states form. These are investigated using pressure, strain and gating.
Achievements
- Spin injection to graphene- Electron optical devices in graphene
- Pressure tuning of moiré superlattice
- Induces spin-orbit coupling in graphene
- Current Phase relation in graphene
