Oscillating Planar Hall Response In Bulk Crystal Of Topological Insulator Sn Doped Bi1.1sb0.9te2s
APPLIED PHYSICS LETTERS(2018)
Abstract
We report the low-temperature magneto-transport in the bulk-insulating single crystal of topological insulator Sn doped Bi1.1Sb0.9Te2S. Shubnikov-de Haas oscillations appear with their reciprocal frequency proportional to cos theta, demonstrating the dominant transport of topological surface states. While the magnetic field rotates on the sample surface, the planar Hall effect arises with sizeable oscillations following a relation of cos theta sin theta. Its amplitude reaches the maximum at the lowest temperature and drops to nearly zero at temperature higher than 100 K. All these evidences consolidate such planar Hall oscillations as another golden criterion on the topological surface transport. Published by AIP Publishing.
