Figure 4

(a) Temperature dependence of the SdH oscillations at θ=0° for the d=2.25 uc sample. (b) Temperature dependence of the scaled oscillation amplitude at B=2.04 T, giving a carrier effective mass of 1.22 me. (c) Dingle plot of the SdH oscillations at 200 mK, giving a total scattering time τ=4.96 × 10−12 s, a related Dingle temperature TD=0.24 K and a consequent quantum mobility μSdH=7.2 × 103 cm2 V−1 s−1.
