%X Using density functional theory-based methods, we report the structural, electronic and topological properties of the FCCcrystal compound TmBi. This material is found to be dynamically stable and shows a non-magnetic semimetallic character. Bytuning the spin–orbit coupling, we observe a significant change in the band structure, and the occurrence of band inversion along − X direction. The parity product at time-reversal invariant momentum points and the Wannier charge center calculations providea topological index Z2 = 1 on the k j = 0 plane (with j = 1, 2 and 3) revealing the non-trivial topological character of TmBi. Theexistence of topologically protected surface states of TmBi through the observation of a Dirac cones at  ̄X point confirms our finding.The present work could inspire platforms for exploring novel topological states within the family of rare-earth monobismuthides:
