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.

在实验和理论相结合的努力中，我们将研究邻近诱导的自旋轨道耦合在石墨烯和过渡金属二硫属化物或3D拓扑绝缘体的异质结构中引起的效应。特别是，我们将阐明扭曲角的作用，使用弱反局域化和自旋输运探测自旋轨道相互作用，并实现基于双层石墨烯的门可控自旋阀。最后，我们的目标是实验证明最近预测的保护边缘状态的石墨烯纳米结构受到邻近诱导的自旋轨道耦合。
