What is it about?
We present spin-to-charge current conversion properties in topological Weyl semimetal TaP (Tantalum Phosphide) at room temperature in which the spin current is generated by spin pumping effect. In addition, we verified that the TaP is much more efficient to convert spin-current into charge-current than other topological materials such as graphene and some 3D topological insulators.

Why is it important?
The high mobility of charged Weyl fermions may find use in conventional electronics and computing. In this context, our findings show that the spin current into electric charge current in the Weyl semimetal TaP works at room temperature, and will thus be essential in combining spin-current technology with conventional electronics based on electric charge currents and involving this promising class of Quantum Materials.

The spin-to-charge current conversion properties in topological Weyl semimetal TaP are investigated by spin pumping effect experiments. The spin-to-charge current conversion is attributed to the inverse Rashba–Edelstein effect occurring at the TaP/ferromagnet interface. In addition, it is verified that the TaP is much more efficient to convert spin current into charge current than other topological materials.
