Abstract
We demonstrate quantum oscillations in [Formula: see text] topological insulator macroflakes in different probe configurations. The oscillation period in the local configuration is twice compared to the non-local configuration. The Aharonov-Bohm-like (AB-like) oscillation dominates the transport property in the local configuration and the Altshuler-Aronov-Spivak-like (AAS-like) oscillation dominates the transport property in the non-local configuration. The AB-like oscillation period is 0.21 T and the related loop diameter is 156 nm which is consistent with the reported phase coherence length in topological insulators. The Shubnikov-de Haas oscillation frequency is the same but oscillation peaks reveal a [Formula: see text] phase shift in the local and non-local configuration. The Berry phase is [Formula: see text] in the local configuration and 0 in non-local configuration.Entities:
