Query: Room temperature spin Hall effect in graphene/MoS$_2$ van der Waals
  heterostructures   Graphene is an excellent material for long distance spin transport but allows
little spin manipulation. Transition metal dichalcogenides imprint their strong
spin-orbit coupling into graphene via proximity effect, and it has been
predicted that efficient spin-to-charge conversion due to spin Hall and
Rashba-Edelstein effects could be achieved. Here, by combining Hall probes with
ferromagnetic electrodes, we unambiguously demonstrate experimentally spin Hall
effect in graphene induced by MoS$_2$ proximity and for varying temperature up
to room temperature. The fact that spin transport and spin Hall effect occur in
different parts of the same material gives rise to a hitherto unreported
efficiency for the spin-to-charge voltage output. Remarkably for a single
graphene/MoS$_2$ heterostructure-based device, we evidence a superimposed
spin-to-charge current conversion that can be indistinguishably associated with
either the proximity-induced Rashba-Edelstein effect in graphene or the spin
Hall effect in MoS$_2$. By comparing our results to theoretical calculations,
the latter scenario is found the most plausible one. Our findings pave the way
towards the combination of spin information transport and spin-to-charge
conversion in two-dimensional materials, opening exciting opportunities in a
variety of future spintronic applications.
