We study the quantum oscillations in the BiSbTe₃ topological insulator. In addition to the Shubnikov-de Haas (SdH) oscillation, the Aharonov-Bohm-like (ABL) oscillations are also observed. The ABL oscillation period is constant at each Landau level (LL) which is determined from the SdH oscillation. The shorter ABL oscillation periods are observed at lower LLs. The oscillation period is proportional to the square root of the LL at temperatures. The ratio of the ABL oscillation period to the effective mass is weak LL dependence. The LL-dependent ABL oscillation might originate from the LL-dependent effective mass.

在拓扑绝缘子中观察Landau依赖水平的Aharonov-Bohm-like振荡。

我们研究了BiSbTe ₃拓扑绝缘体中的量子振荡。除了Shubnikov-de Haas（SdH）振荡外，还观察到了类似Aharonov-Bohm的（ABL）振荡。由SdH振荡确定，每个BLAU振荡周期在每个Landau电平（LL）处都是恒定的。在较低的LLs处观察到较短的ABL振荡周期。在温度下，振荡周期与LL的平方根成正比。ABL振荡周期与有效质量的比率是弱的LL依赖性。LL依赖的ABL振荡可能源自LL依赖的有效质量。
