| Abstract | The magneto-transport properties of a series of Bi-2(TexSe1-x)(3) films are investigated. It is seen that the doped samples develop an insulating behavior at low temperatures upon the increasing doping level as compared to the pristine sample Bi2Se3. The field evolution of the magneto-resistance (MR) under perpendicular and parallel magnetic fields for Bi-2(TexSe1-x)(3) films with x = 0, 0.1, 0.24, 0.4, and 0.6 at temperatures from 2 to 200 K is investigated. A low field cusp behavior appears in MR data of Bi-2(Te0.1Se0.9)(3) film, which is associated with the weak anti-localization (WAL). In Bi-2(Te0.4Se0.6)(3) films, MR with perpendicular and parallel magnetic fields shows signatures of WAL at low magnetic fields. A remarkable negative behavior, similar to weak localization (WL), under a high magnetic field parallel to the film surface is found which is dominated by bulk-state electrons. MR of Bi-2(Te0.6Se0.4)(3) film reveals a low-field WAL behavior and a high-field parabolic behavior, revealing a two-dimensional magneto-transport property. |
