Magnetoresistance measurements and fitting results of the magnetoconductivity in perpendicular magnetic fields. (a) Normalized MC of the single layer (Bi2Se3) sample (squares) and bilayer (Bi2Se3:Sb/CFO) samples (circles) at 2 K in the low field region. (b) The fitted Δ/2E F with different Sb doping. (c) The fitted phase coherence length with different Sb doping. (d) and (e) display the fitted α 1 (upper panel) and α 0 (lower panel) as a function Sb ratio.
