The high-field galvanomagnetic effects in bicrystals of 3D topological insulator Bi 1-x - Sbx (0. 07 ≤ x ≤ 0.15)

Abstract

We report the results of the investigations at He-liquid temperatures of the galvanomagnetic effects of twisting bicrystals of 3D topological insulator (TI) Bi1−xSbx (0.07 < x <0.15) to elucidate the peculiarities of electronic system behaviour in ultraquantum limit (UQL) of magnetic fields. The bicrystals, consisting of two single crystalline blocks and a crystallite interface (CI), were obtained by the zone recrystallization method using the double seed technique.
