Researchers from Europe developed heterostructures built from graphene and topological insulators and have shown the strong tunability and suppression of the spin signal and spin lifetime in these structures.

Associate Professor Saroj Prasad Dash from Chalmers University of Technology explains that the advantage of using heterostructures built from two Dirac materials is tha graphene in proximity with topological insulators still supports spin transport, and concurrently acquires a strong spin–orbit coupling.
