What is it about?
In the last decade, van der Waals materials and heterostructures came in the limelight. Thousands of materials with different properties were identified and they can be combined to modify the properties even further.We investigated the Electron Spin Resonance (ESR) in a Graphene/MoS2 device and found that the g-factor of graphene is modified due to its proximity to MoS2 and this indicates proximity induces Spin-Orbit Coupling (SOC) in graphene.

Why is it important?
It is possible to assemble a large number of different vdW materials in order to tailor a system with specific properties, thus bringing together the best of “many worlds.” Graphene is a material with excellent conductivity, but small spin-orbit coupling (SOC) restricts its use in applications like Spintronics. By coupling it with MoS2, we show that the g-factor is modified indicating an enhanced SOC in the system.
