Quantum Oscillations from Surface States in Cd₃As₂Nanowires

Topological Dirac and Weyl semimetals have topological surface states called Fermi arcs. Extensive efforts have been made toward the observation of novel topological transport phenomena induced by the Fermi arc. However, surface-state-induced quantum oscillations have not been demonstrated in nanowires of TDSMs. Here, we report the observation of surface Shubnikov-de Haas oscillations in submicron wires of TDSM Cd₃As₂ grown by a chemical vapor deposition method. Our results will facilitate the further study of quantum transport phenomena in topological nanowires.
