Query: Large multi-directional spin-to-charge conversion in low symmetry
  semimetal MoTe$_2$ at room temperature   Efficient and versatile spin-to-charge current conversion is crucial for the
development of spintronic applications, which strongly rely on the ability to
electrically generate and detect spin currents. In this context, the spin Hall
effect has been widely studied in heavy metals with strong spin-orbit coupling.
While the high crystal symmetry in these materials limits the conversion to the
orthogonal configuration, unusual configurations are expected in low symmetry
transition metal dichalcogenide semimetals, which could add flexibility to the
electrical injection and detection of pure spin currents. Here, we report the
observation of spin-to-charge conversion in MoTe$_2$ flakes, which are stacked
in graphene lateral spin valves. We detect two distinct contributions arising
from the conversion of two different spin orientations. In addition to the
conventional conversion where the spin polarization is orthogonal to the charge
current, we also detect a conversion where the spin polarization and the charge
current are parallel. Both contributions, which could arise either from bulk
spin Hall effect or surface Edelstein effect, show large efficiencies
comparable to the best spin Hall metals and topological insulators. Our finding
enables the simultaneous conversion of spin currents with any in-plane spin
polarization in one single experimental configuration.
