Image of FIG. 1.
FIG. 1.

(a) X-ray diffraction pattern (θ-2θ scan) of a Bi2Te3 film grown on SrTiO3 substrate; the inset shows the rocking curve of the (0006) peak. (b) EDX mapping of the film showing the spatial distribution of Bi (blue) and Te (red). The scale bar is 500 nm.

Image of FIG. 2.
FIG. 2.

(a) The Hall resistance as a function of magnetic field; the inset shows a schematic drawing of the band structure of Bi2Te3. (b) The magnetoresistance (MRxx) as a function of magnetic field at 1.5 and 30 K; the solid red lines are guides to the eye; the inset shows low field MR taken at different temperatures revealing the weak anti-localization effect.

Image of FIG. 3.
FIG. 3.

A fit to the magneto-conductivity data at 1.5 K (a) and 30 K (b) using Eq. (1) (green) and Eq. (2) (blue). The insets are the zoom-in view at low fields (the regions marked by the dashed rectangles).
