Defect-induced negative magnetoresistance and surface state robustness in the topological insulator BiSbTeSe2

Absence of backscattering and occurrence of weak antilocalization are two characteristic features of topological insulators. We find that the introduction of defects results in the appearance of a negative contribution to magnetoresistance (MR) in the topological insulator BiSbTeSe2 at temperatures...
