【 摘 要 】

We present a study on magnetotransport in films of the topological Dirac semimetal Cd3As2 doped with Sb grown by molecular beam epitaxy. In our weak antilocalization analysis, we find a significant enhancement of the spin-orbit scattering rate, indicating that Sb doping leads to a strong increase of the pristine band-inversion energy. We discuss possible origins of this large enhancement by comparing Sb-doped Cd3As2 with other compound semiconductors. Sb-doped Cd3As2 will be a suitable system for further investigations and functionalization of topological Dirac semimetals.
