Abstract

This paper demonstrates electrical creation of spin polarization in a layered semimetal TaTe${}_{2}$ via the charge-spin conversion process at room temperature. Using a hybrid device of TaTe${}_{2}$ in a van der Waals heterostructure with graphene, the spin-polarization in TaTe${}_{2}$ is injected and detected by nonlocal spin-switch, Hanle spin precession, and inverse spin Hall effect measurements.
