Carrier density for the (Sb2Te3)1−x(MnSb2Te4)x samples. (a) Measured carrier density (C.C.) for a selection of samples including pure Sb2Te3 (green circle), Mn doped Sb2Te3 (orange shaded area) and (Sb2Te3)1−x(MnSb2Te4)x (purple shaded area) with dashed line drawn to express the trend of the change in carrier density of the samples. Carrier density for all the samples was measured at 2 K except for Sb2Te3 (green circle), which was measured at 10 K (b) Field dependent Hall resistance (Rxy) measurement of a sample taken at 2 K up to 9 T. Dashed red line drawn to show the linear part of the plot. (c) High-angle HAADF STEM images of a Mn doped Sb2Te3 sample and a representative sample containing QL and SLs. The QLs and SLs are marked by white and purple labels, respectively.
