Abstract | Recent theories predicted that 1T'-MoTe2 is a higher-order topological insulator (HOTI) exhibiting one-dimensional (1D) conducting edge states, and that Td-MoTe2 becomes a HOTI with broken inversion symmetry under strain or lattice distortion. Here, we report the transport evidence for 1D helical edge states in MoTe2 thin flakes. Under an in-plane magnetic field perpendicular to the current, Altshuler-Aronov-Spivak interference of edge states is observed, in which the oscillating period corresponding to magnetic flux h/2e agrees with the lateral cross-sectional area. The absence of Aharonov-Bohm interference stems from the helical nature of the edge states. Temperature evolution of the fast Fourier transform amplitude is further obtained, indicating the quasiballistic transport mode. Our work deepens the understanding of higher-order topological properties of MoTe2, paving the way for further topological electronics. |
