Advanced Spin Transport and Protected Edge States in Graphene-Based Proximity Structures (A09)

• Subject Area: Experimental Condensed Matter Physics ; Theoretical Condensed Matter Physics
• Term: since 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 314695032

In a combined experimental and theoretical effort we will study effects caused by proximity-induced spin orbit coupling in heterostructure of graphene and transition metal dichalcogenides or 3D topological insulators. In particular, we will elucidate the role of the twist angle, using weak antilocalization and spin transport to probe spin-orbit interaction, and realize a gate-controllable spin valve based on bilayer graphene. Finally, we will aim for experimental proof of recently predicted protected edge states on graphene nanostructures subject to proximity-induced spin-orbit coupling.
